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.

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 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.
