Special File Command Tags

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

Important Note:

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

File Command Tag	Description	Supported Platform
[ADO]	Microsoft SQL Server Interface	Windows only
[DB2]	DB2 Support	Any system
[DDE]	Dynamic Data Exchange	Windows and WindX
[DLL]	Dynamic Link Library	Windows and WindX
[HTTP / HTTPS]	Remote Call to Apache Server	Any system
[LCL]	Access User's Local Machine	Any platform via WindX
[LIB]	Program Library	Windows only
[MYSQL]	Open MySQL Native Database Link	Windows, some UNIX/Linux
[OCI]	Connect to Oracle Server	Windows, some UNIX/Linux
[ODB]	Open Database	Windows and 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 PxPlus thin-client graphical user interface screen handler, is used to:

   • Give a Windows graphical user interface 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.
