NOMADS Variables |
|
Your program can gain access to NOMADS reserved variables for NOMADS objects when you include Call, Perform or Execute processing in the NOMADS Panel Designer (i.e. the Logic tab if using NOMADS Folder Style or the Events group if using NOMADS Property Sheets). When you select Call as in the Events Logic, only non-global variables specified in the Call's parameter list are available to your called program.
NOMADS makes the variables that are listed below available to your program. (This list also includes Query Variables.)
The NOMADS Environment Maintenance utility provides one central location to display and set the %NOMADS Properties used by the %NOMADS object (*obj/nomads.pvc) to control the behavior of different aspects of the NOMADS environment.
(The NOMADS Environment Maintenance utility was added in PxPlus 2020.)
This table lists the control-related variables that are available in the NOMADS environment:
|
Control Variables |
Description |
|
For these variables, xxxxxx represents the control name: | |
|
xxxxxx{.VAL}$ |
Control value (.VAL can be suppressed). |
|
xxxxxx.CTL |
CTL value for the control. |
|
xxxxxx.DATASET |
(Chart Controls Only) Contains current dataset for a chart. |
|
xxxxxx.NOCHANGE |
NOMADS will decrement the CHANGE_FLG variable using the value in xxxxxx.NOCHANGE. |
|
xxxxxx.ROW |
(Grid Controls Only) Contains the current row and column being processed in a grid. |
|
xxxxxx.TAG$ |
User defined tag value as per the control definition. |
The NOMADS engine (*winproc) creates and monitors many special reserved variables that make information available to your routines or can be used to alter NOMADS behavior.
This table lists the reserved NOMADS variables that are available to your programs:
|
NOMADS Reserved Variables |
Description | ||||||
|
_EOM$ |
Contains the Hex code of the key that triggered the last control; e.g. $02$ = double click, $09$ = Tab key. | ||||||
|
ALTERNATE_PANEL$ |
Contains the panel name to be used for Alternate Panel Layouts. | ||||||
|
ALTERNATE_PANEL_TYPE$ |
If one alternate panel is used, then this variable should be set to a value of "M" if the panel is not part of a folder control or "F" if the panel is in a folder control. See Alternate Panel Layouts. | ||||||
|
ARG_1$ … ARG_20$ |
You can pass a maximum of 20 arguments when you select the Link command or use the PROCESS and CALL directives to call another panel. NOMADS places the values in the corresponding reserved variables, ARG_1$, ARG_2$ ... to ARG_20$ and makes these values available to your panel. | ||||||
|
CHANGE_FLG |
Non-zero value whenever a control changes on a panel. NOMADS increments this variable automatically whenever the value in a control changes, allowing you to detect change. NOMADS does not reinitialize this variable; therefore, you should reset it to 0 (zero) in your program(s) when required. If you do not want the CHANGE_FLG variable to be updated when a control value is changed, select the Ignore Change Flag check box property for the control in the NOMADS Panel Designer. (The Ignore Change Flag check box property was added in PxPlus 2017.) | ||||||
|
CMD_STR$ |
Logic to be executed next. Set using the following values: • "END" or "E" to terminate the current panel. • "ENDPANEL,panelname,library" or "ENDPANEL panelname library" to terminate a concurrent panel. (Library is optional.) • "Jpanelname[ ,library]" to JumpTo another panel. • "Upanelname [ ,library]" to launch a concurrent window. (Library is optional.) • "ENDALL" or "A" to close all active windows (used with concurrent windows). Note: | ||||||
|

The list consists of full pathnames of the dragged files, separated by a SEP character. See Drag and Drop Utility. (The DROPFILES$ variable was added in PxPlus 2021 Update 1.) | |||||||
|
Query variable. Contains the contents of the entire main file record. Can be used in Selection Logic or in Return Value expressions. (The Query Subsystem uses the REC( ) function to obtain this value.) You can use this variable alone or in conjunction with PRIME_KEY$. Example: PRIME_KEY$+ENTIRE_RECORD$ (The ability to use the ENTIRE_RECORD$ variable in Selection Logic also was added in PxPlus 2024 Update 1.) | |||||||
|

|
IGNORE_EXIT$ |
If set to a "Y" value, the window close/F4 key is ignored. If set during panel On Exit logic, the panel will not be closed. NOMADS resets this variable to null after On Exit logic. | ||||||
|
Set to 1 to suppress the next popup menu. Usually set conditionally in the Prior Popup logic of the Assign Popup Menu dialogue. Automatically reset to 0 after the popup has been skipped. (The IGNORE_POPUP variable was added in PxPlus 2020.) | |||||||

|
NEXT_ID$ |
If NEXT_ID is loaded with a value other than -1, then the variable named in NEXT_ID$ will be evaluated and its value used as NEXT_ID. This is used in conjunction with NEXT_FOLDER to set focus to a control on a Folder that is about to become active. By default, when you set NEXT_ID, the system will clear the input queue unless the NOMADS variable NO_FLUSH is set. Example: NEXT_FOLDER=FLDR.FOLDER3.CTL,NEXT_ID=0, | ||||||
|
NO_FLUSH |
Do not clear input when NEXT_ID is set. | ||||||

|
%SCR_DEF_H_FL$ |
Default Help file. |
|
%SCR_DEF_H_ID$ |
Default Help ID. |
|
%SCR_LIB |
Screen library file number. |
|
%SCR_LIB$ |
Screen library path. |
This table lists the methods that are used by the %NOMADS object:
|
%NOMADS Methods |
Description | ||||||||
|
%NOMADS'AddCTL |
Provides the ability to dynamically add CTL logic to panels. Formats:
Example: The following example could be used to set the OnTipCtl for dynamically created controls such as Buttons: Btn_id = %NOMADS'AddCtl("Do_Button", _obj) (The %NOMADS'AddCTL method was added in PxPlus 2019.) |
The *obj/nomads class was created to hold NOMADS and iNomads-based parameters and settings. Its purpose was to use property settings to replace the global variables prefixed with %NOMAD_ or %NOMADS_ that had generally been used to control the behavior of different aspects of the NOMADS environment.
(The *obj/nomads class was added in PxPlus v11.00.)
The *obj/nomads class is automatically instantiated when the NOMADS environment is invoked. The reference to this object is loaded into the %NOMADS global variable when it is created. Its properties and methods can then be accessed using the %NOMADS variable as the object identifier.
When the class is instantiated, the values' existing variables prefixed with %NOMAD_ or %NOMADS_ are automatically loaded into the corresponding properties and can be accessed either as a property or using the original global variable name. This means that NOMADS variables that you have set in a legacy START_UP program, for example, do not have to be changed to property references. If, however, you choose to use property references in a START_UP program, you would have to instantiate the *obj/nomads class first, as it would not yet exist at this time.
Example:
Below are some sample lines from a START_UP program using the %obj/nomads class:
X=NEW("*obj/nomads") !Instantiate the %NOMADS object
%NOMADS'VISUAL_OVERRIDE=4
%NOMADS'CHART$="google"
%NOMADS'QRY_BTN$="{!16X16/Buttons/Help}"
%NOMADS'QRY_WIDE=3
This is the same as:
%NOMAD_VISUAL_OVERRIDE=4
%NOMAD_CHART$="google"
%NOMAD_QRY_ BTN$="{!16X16/Buttons/Help}"
%NOMAD_QRY_WIDE=3
NOMADS Environment Maintenance Utility
The NOMADS Environment Maintenance utility is used to set and maintain %NOMADS Properties used by the %NOMADS object (*obj/nomads.pvc) to control the behavior of different aspects of the NOMADS environment.
On instantiation, the %NOMADS object checks the property values that were set with this utility.
(The NOMADS Environment Maintenance utility was added in PxPlus 2020.)
%NOMADS Properties
Many NOMADS global variables affect the entire application, such as %NOMAD_Enter_Tab that regulates the behavior of the Enter key or %NOMAD_Object_Resize that turns on object resizing at the application level. These variables are generally set during the initialization phase of the application itself (such as in the START_UP program) rather than as part of an event-handler routine.
Some NOMADS global variables affect event logic, such as %NOMADS_Pre_Display$ and %NOMADS_OnExit$ that specify optional panel pre-display and exit routines or %NOMADS_Post_Display that allows you to override the sequence of the Post Display logic when there are Folders on a panel.
This table lists the available properties and their possible values, which can also be viewed by loading and listing the class program "*obj/nomads.pvc":
|
Description | ||||||||||||||||
|
%NOMADS'Activation_Ok |
(Not Used in PxPlus) *winproc checks if the activation corresponds to the NOMADS version and displays a message if it is incorrect.

Example:
%NOMADS'ourCompanyLogo$="images/CompanyLogo.gif"
This will add an 'ourCompanyLogo$ property to the object.
Example 1: Using NOMADS Variables to Pass and Store Values
This example of a panel and its associated event-handler routines shows how various NOMADS variables can be used to pass and store values and affect behavior.
A panel named PRODCODE has been created to enter and validate a product code. It has a Multi-Line called PRODUCTCODE and two buttons, OK and Cancel. The Panel Header has a default program set and Pre_Display logic that is set to perform ";PC _Pre_Display".
The PRODUCTCODE Multi-Line has an Input Length of 1, the Uppercase attribute is turned On, Initial Value is set to X, and On Change Logic is set to perform ";PC_Validate_ProductCode". The On Change event for the OK button is set to perform ";PC _Okay". The On Change event for the Cancel button is set to END. The event-handler routines are as follows (NOMADS variables are marked in bold text):
! Process ProdCode panel
!
PC_Pre_Display:
if Arg_1$="" \
then ProductCode$=Init_Val$ \
else ProductCode$=Arg_1$
Arg_1$=""
return
!
PC_Validate_ProductCode:
if ProductCode$="" \
then ProductCode$=Init_Val$ \
else if pos(ProductCode$="ADPX")=0 \
then msgbox "Invalid product code"+sep+"Valid entries are A, D, P and X","Error";
ProductCode$=Prior_Val$;
Next_ID=ProductCode.ctl;
Refresh_Flg=1
return
! PC_Okay:
Arg_1$=ProductCode$
Cmd_Str $="END"
return
Example 2: Using NOMADS _EOM$ Variable to Filter Events
This example shows how the _EOM$ variable can be used to filter events and control the behavior of the interface. Normally, On Change logic is triggered when the user changes the value of a control and then either presses the Enter key or moves focus to another control. In the case of a List Box control, double-clicking on an item with the mouse also triggers On Change logic.
In the panel below, we want to select a client from the List Box on the left either by highlighting an item and pressing the Enter key or by double-clicking on the item. We want to filter out the On Change logic triggered when the List Box is exited.
A default program is assigned in the Panel Header, as well as Pre-Display and Exit logic, and Auto Refresh is set.
The Multi-Lines on the right side of the panel are named using data field names and are loaded when the data file is read. The properties for the List Box are defined as follows:
|
|
Property |
Value |
|
|
Control Name |
CLIENTLIST |
|
|
Control Type |
List Box |
|
|
List Box Type |
Report View |
|
|
On Change |
Perform=";Process_CLIENTLIST" |
|
|
Post Create |
Perform=";Load_CLIENTLIST" |
|
|
Alt-Key |
$ |
|
|
Format Definition |
[Client Name]L20.00,[Client ID]L8.00, |
|
|
Full Line Highlight |
On |
We also want to restrict the Client List to a specific sales representative so the Sales Rep Code is passed as Arg_1$:
PANEL_PREDISPLAY:
sRep$=arg_1$ ! Sales Rep to be processed passed in as Arg_1$
PanelTitle$="Client Information for "+sRep$ ! Set title for panel
channel=0
open (hfn,iol=*,err=*return)"client";
channel=lfo
return
!
PANEL_EXIT:
if channel<>0 \
then close (channel)
return
!
LOAD_CLIENTLIST:
list_box load ClientList.ctl,"" ! Clear the list box
select * from channel,kno=1 where SalesRep$=sRep$ ! sRep$ records only
list_box load ClientList.ctl,0,ClientName$+sep+ClientID$ ! Load list box
next record
read data from "" to iol=iol(channel) ! Clear the multi_lines
return
!
PROCESS_CLIENTLIST:
! Process only if list item selected by CR ($0D$) or doubleclick ($02$)
if _eom$=$0D$ or _eom$=$02$ \
then read data from ClientList$ to ClientName$,ClientID$;
read (channel,kno=1,key=ClientName$:ClientID$)
return
Example 3: Using Folder Variables
In applications that use Folder controls, you may want to set focus to a control on a different tab. This can be accomplished by using the NOMADS variables FOLDER_ID$, NEXT_FOLDER, NEXT_ID and NEXT_ID$.
This example shows a panel with a Folder control consisting of three tabs: Shipto Information, Payment and Details. The Payment tab contains a Multi-Line called SALESREP.
Shipto Information tab:
Payment tab:
The On Change event for the Write button will validate the SALESREP Multi-Line. If the Multi-Line is empty, a message box will display and focus will be set to the control:
WRITE_REC:
if Salesrep$="" \
then msgbox "SalesRep Id is mandatory","Error";
if Folder_Id$<>"Payment" \
then Next_Folder=Fldr.Payment.Ctl;
Next_Id=0,Next_Id$="Salesrep.ctl" \
else Next_Id=Salesrep.ctl
Refresh_Flg=1
return
