AutoEnablePDF=0 | 1

Controls the default setting of the 'AP' system parameter.

BlinkTime=nnn

Number of milliseconds between blinks for blinking text on graphical windows devices. (Default is 500ms.)

BrowserDebug

Controls whether or not the browser developer console will display in a popup window for any subsequently created *BROWSER controls. See the 'OPTION' mnemonic BrowserDebug setting.

(This functionality was added in PxPlus 2021.)

BrowserLang=language code

Forces the embedded Chromium browser language to be language code. See Language Codes for a list of supported languages and codes.

Defaults to user OS language unless PRINT 'OPTION'("BrowserLang") is used to override. See the 'OPTION' mnemonic BrowserLang setting.

(This functionality was added in PxPlus 2019.)

ButtonCursor=n

Cursor number to be used when the pointer is over a button.

ButtonDisableCursor=n

Cursor number to be used when the pointer is over a disabled button.

Certificates=IGNORE | VALIDATE | TRUSTREQD

(Applicable to Client Connections Only)

Defines the default certificate validation rules:

IGNORE

(Default) Performs no validation of the certificate(s) presented by the server.

VALIDATE

Indicates that you want the certificate validated (expiry dates, etc.) but is not required to have been issued by a trusted supplier (i.e. it could be self-signed).

TRUSTREQD

Validates that the certificate came from a trusted vendor and that the certificate host name must match.

(This functionality was added in PxPlus 2017.)

CertStore=pathname

Defines the location of the trusted certificate store file or directory. The default certificate store is the ca-bundle.crt file in the PxPlus install directory. The latest version of this file is downloaded from the following location: https://raw.githubusercontent.com/bagder/ca-bundle/master/ca-bundle.crt.

If directory, the last character must be a directory delimiter (/ or \).

See the OpenSSL documentation on the SSL_CTX_load_verify_locations function for contents at the following link:

https://www.openssl.org/docs/man1.0.1/ssl/SSL_CTX_load_verify_locations.html

(This functionality was added in PxPlus 2017.)

CommandLine=text -prm -prm .

Optional argument used to define the Command line to be used when running PxPlus. This argument is used only when an INI file is specified. Its contents replace the INI file name in the original command sequence.

Warning! 
The CommandLine= parameter overrides any Command line used to launch PxPlus. This can have adverse effects on programs such as *NTHOST/*NTSLAVE, the Application Server, *WINDX.UTL;SPAWN and *Server;Spawn.

Cursorn=text

Overrides settings for the graphic display of the mouse pointer (as controlled via the 'CURSOR' mnemonic).

Where:

n identifies a cursor number to override and text specifies the pointer to use.

text value can be the name of a valid resource within an associated resource library or an * (asterisk) followed by a standard system cursor name. These are represented as follows:

*

Standard arrow (IDC_ARROW)

*appstart

Standard arrow and small hourglass (IDC_APPSTARTING)

*arrow

Standard arrow (IDC_ARROW)

*cross

Crosshair (IDC_CROSS)

The IDC value, shown in parenthesis, represents the corresponding Windows LoadCursor API resource identifier.

Example:

In the following example, cursor #5 ('CURSOR'(5) mnemonic) is changed to the standard Windows Hand mouse pointer:

  Cursor5=*hand 

The following INI entries can be used to reset cursors #5 and #6 to their pre-V7.50 states:

  Cursor5=PvxPush 
  Cursor6=PvxNoPush

Debug=n

Enables access to the debugging environment windows. Values are:

 0

(Default) Debugging available if no lead program specified - no debugging windows if a lead program is given.

 1

Debugging windows are always available.

-1

Debugging windows are never available.

DebugPlus

Deprecated -- No Longer in Use

DebugPlusOpt=n

Set by the system to store the various options enabled in the Trace window.

Fid0=text

Override setting of FID(0).

ForceMessageBoxOnTop= -1 | 1

When set to 1, this forces a message box to display on the desktop when running as a service. A -1 does not display the message box and automatically selects the OK button.

Note:
By selecting '1', MSGBOX TIM will no longer work.

GetFileDelim=hh

Defines the character to be used between each file name passed in a GET_FILE_BOX. See 'GS' system parameter.

Value is the Hex code for the character to use.

Library=path

Path name to PxPlus library location (e.g. ".. PXPLUS\LIB").

LogFile=xxx

Defines the text file to receive the internal system error log. The log file must already exist, as the INI file will not create it.

When specifying, include the full absolute pathname of the log file (without quotes).

When defining the log file, you can specify the maximum file size (in megabytes) that you want the log file to grow. See PxPlus Log File.

PDFEmbed=x

Controls whether PDF fonts are to be embedded in system-generated PDF documents. Options are:

ShutdownMsg=text

Three possible options for this parameter are:

Text

Specifies text to appear in a message box when the user attempts a shutdown and a PxPlus session is still running.

^Text

Same as =Text, except that the user is not able to exit PxPlus.

*ignore*

Allows PxPlus to be exited while a program is running without asking if the user really wants to shut down. This is for applications that run in the background or as NT services.

SysMenun =[&]text=nnn

Allows up to 10 custom items to be added to the drop down menu that appears when you click on the icon in the upper left corner of the base PxPlus launch window.

Where:

[ODBC], [OCI] and [DB2] Sections

Each of these section headings can be inserted into the PXPLUS.ini file to manually override specific defaults. The [ODBC], [OCI] and [DB2] INI parameters and settings are described along with corresponding SQL keywords (if available).

ACCESS=READ | WRITE

ODBC & DB2 - Determines type of file access required. Default is WRITE.

SQL keywords: SQL_ACCESS_MODE, SQL_MODE_READ_ONLY, SQL_MODE_READ_WRITE

AUTOCOMMIT=ON | OFF

ODBC & DB2 - Determines auto commit functionality of the database driver. It is applicable only if the driver supports transactions.
 
SQL keywords: SQL_AUTOCOMMIT, SQL_AUTOCOMMIT_ON, SQL_AUTOCOMMIT_OFF

CHECK_DATES=Y | N
CHECK_NUMERICS=Y | N
CHECK_LENGTH=Y | N


ODBC - Determines the type of data validation required.

Setting these to "Y" enables run time checking of Dates (must match DATEFMT= setting), Numeric (must have the proper number of digits before/after the decimal point), and Length (must be less than or equal to the length of the field).

Note:
The Check_Date only takes effect if they also have a DATEFMT= specified for the ODBC. For the Date validation, the minimum year is 1500.

CONCURRENCY=READONLY | LOCK | OPT_VERSION | OPT_VALUE

ODBC & DB2 - Determines the type of concurrent access control/locking to be used.

READONLY sets the cursor; is set to Read Only - no updates allowed.

LOCK applies low-level record locking.

OPT_VERSION causes optimistic locking with the database version control to be used.

OPT_VALUE causes optimistic locking with comparing record/column values to be used.

SQL keywords: SQL_CONCURRENCY, SQL_CONCUR_READ_ONLY, SQL_CONCUR_LOCK, SQL_CONCUR_ROWVER, SQL_CONCUR_VALUES

CURSOR_TYPE=FORWARD | STATIC | KEYSET | DYNAMIC

ODBC & DB2 - Defines the type of cursor that is to be used.

FORWARD indicates that any result sets can be read in a forward only direction.

STATIC indicates that the result set is static.

KEYSET forces the cursor to use/maintain record keys in a keyset.

DYNAMIC indicates that the cursor is effective in the current row set only.

SQL keywords: SQL_CURSOR_TYPE, SQL_CURSOR_FORWARD_ONLY, SQL_CURSOR_STATIC, SQL_CURSOR_KEYSET_DRIVEN, SQL_CURSOR_DYNAMIC

CURSOR_USE=DRIVER | ODBC | IF_NEEDED

ODBC & DB2 - Controls the type of cursor to be used within the ODBC connection.

DRIVER (Default) assumes the specific driver's own cursors.

ODBC causes the ODBC interface to use the "Driver Managers" cursor library that may provide additional functionality not available within the database driver.

IF_NEEDED tells the system to use the specific database driver's own cursor functionality unless the additional functionality is requested specifically.

SQL keywords: SQL_ODBC_CURSORS, SQL_CUR_USE_DRIVER, SQL_CUR_USE_ODBC, SQL_CUR_USE_IF_NEEDED

DATEFMT=text 

ODBC, OCI & DB2 -
String mapping of date format to be returned. Applies to all date fields in table.

DB=dbname or QUALIFIER=dbname 

ODBC Only -
Qualifies the specific database that you wish to use when using a driver to service multiple databases.
 
SQL keyword: SQL_CURRENT_QUALIFIER

DEBUGIT=text 

ODBC, OCI & DB2 -
String to append to SQL statement along with program name and line number for debugging purposes.

text must be the comment character(s) appropriate to the database.

Example:

 "-" is the comment identifier for Microsoft SQL Server; anything after -- is ignored by SQL Server when compiling the SQL statement.

EXTROPT=text 

ODBC, OCI & DB2 -
Controls the format of the SELECT statement used to process an EXTRACT.

By default, PVX generates a SELECT * FROM table FOR UPDATE WHERE... If specified, then text is substituted in place of FOR UPDATE. In addition, if the first character of text is $, then the remaining characters of text are placed at the end of the SELECT statement rather than after the file name. This allows for different variations of SQL to be supported.

ISOLATION=UNCOMMITED | COMMITED | REPEATABLE | SERIAL | VERSIONING

ODBC & DB2 - Controls the isolation that this connection will have relative to other processes on the same database.

In particular, it controls Dirty reads (reading data that may be rolled back), Non-Repeatable reads (reading data after being changed by other transactions), and Phantom reads (reading data newly added to file).

Settings include:

  UNCOMMITED (D, R, P possible)
  COMMITED (D possible, R & P not possible)
  REPEATABLE (P possible, D & R not possible)
  SERIAL (D, R, & P not possible)
  VERSIONING (D, R, & P not possible, but uses versioning as opposed to record locks)

SQL keywords: SQL_TXN_ISOLATION,SQL_TXN_READ_UNCOMMITTED, SQL_TXN_REPEATABLE_READ, SQL_TXN_SERIALIZABLE, SQL_TXN_VERSIONING

KEYSET_SIZE=

ODBC & DB2 -
Size of the key set for use with the cursor.

SQL keyword: SQL_KEYSET_SIZE

MAXROWS=

ODBC & DB2 -
Maximum number of rows/records returned.
 
SQL keyword: SQL_MAX_ROWS

NULLPADKEY=

ODBC, OCI & DB2 -
Set to force keys to be padded to full length with the null character, $00$. x can be 1, Y or y. Use NULLPADKEY=N to turn off this behavior.

ORACLE=Y | N

ODBC & OCI - Indicates if the database uses ORACLE SQL sequence.

If ORACLE= and TOP= are used, then SELECT commands are generated as SELECT * FROM (SELECT * FROM TABLE) WHERE ROWNUM < 1.

Defaults: ORACLE=Y (under [OCI]), ORACLE=N (under [ODBC]).

POSUPDATE=x

ODBC & DB2 - Use one of the following:

M

Must use positioned update

O

(Default) Optionally use positioned update

N

Never use positioned update

PREPARE=

ODBC, OCI & DB2 -
Set to use prepared statements. x can be 1, Y or y. Use PREPARE=N to turn off this behavior. Prepared statements are pre-compiled SQL that may improve performance.

PSWD=text 

ODBC, OCI & DB2 -
Default password. Used if no password supplied on OPEN.

Warning! 
The above setting is not secure. Anyone with access to the INI can read the password.

ROWSET_SIZE=

ODBC & DB2 -
Size of the row set used by the cursor.

SQL keyword: SQL_ROWSET_SIZE

TEXTMAX=

ODBC & DB2 -
Defines the maximum length of a returned column. Default is TEXTMAX=4096.

TIMEOUT=

ODBC & DB2 -
Timeout value for any SQL operation (time before error 0 returned).
 
SQL keyword: SQL_QUERY_TIMEOUT

TOP=

ODBC, OCI & DB2 -
If specified, then PxPlus uses the TOP keyword in all SELECT statements, where possible.

If n is non-zero, then the KEF( ) and KEL( ) functions issue a SELECT TOP 1... SQL statement, which improves system performance.

If n > 0, then PVX issues SELECT TOP n to reduce the data transferred.

TOP= -1 indicates the driver supports TOP; however normal reading should not use it.

Default is 0 (zero) - TOP not supported.

UNIQUE=

ODBC, OCI & DB2 -
Set for new opens to be on a unique connection. x can be 1, Y or y. Use UNIQUE=N to turn off this behavior.

USER=text 

ODBC, OCI & DB2 -
Default user ID. Used if no user ID is supplied on OPEN.

Debug Sections

Debug windows and their respective settings from PxPlus' Windows Debug Environment are saved in the INI file under the following section headings:

[TraceWindow]
[WatchWindow]
[BreakWindow]
[CommandWindow]
