Special Command Tags
Overview  
  Special command file tags (enclosed in square brackets) are used to modify paths and filenames for specific I/O uses in ProvideX. They may include a series of semicolon- separated parameters to be processed at run time. Some of these tags are supported only in specific operating environments.


*Important* The square brackets enclosing special tags are part of the syntax. Other square brackets in syntax examples indicate that elements are optional.


  This chapter covers the following special command tags:

File Command Tag Description Supported Platform
[DDE] Dynamic Data Exchange Windows & WindX.
[DLL] Dynamic Link Library Windows & WindX.
[LIB] Program Library Windows only.
[LCL] Access users local Machine Any platform via WindX
[MYSQL] Direct Connect to MySql Windows, some UNIX/Linux.
[OCI] Connect to Oracle Server Windows, some UNIX/Linux.
[ODB] Open DataBase Windows & WindX.
[RPC] Remote Process Control Any system
[TCP] Transmission Control Protocol Any system
[WDX] Direct Action to Client Machine Any platform via WindX.


*Note* [WDX] specialty commands can only be used when running under WindX. You can also prefix some (but not all) of the other specialty command tags with a [WDX] tag to direct the action to the WindX client machine instead of the server.

WindX, the ProvideX thin-client GUI screen handler, is used to:

  • give a Windows GUI look to character-based applications
  • optimize a network's use of both Windows and UNIX by directing tasks to the most appropriate platform
  • provide remote processing through serial and/or TCP/IP communications
