Using SDSF with the REXX programming language
This topic describes how to access SDSF data and function with the REXX programming language, and how to protect the use of SDSF through REXX.
Using SDSF with REXX provides a simpler and more powerful alternative to using SDSF in batch, which is described in Using SDSF in batch.
| To: | Use: | For more information: |
|---|---|---|
| Add and delete the SDSF host command environment | ISFCALLS() | Adding the SDSF host command environment with ISFCALLS |
| Issue SDSF commands to access tabular panels and other information | ISFEXEC | Issuing commands with ISFEXEC |
| Issue action characters and overtype columns | ISFACT | Issuing action characters and modifying columns with ISFACT |
| Browse output | ISFBROWSE or ISFACT and special variables | Browsing output |
| Print output | ISFACT and special variables | Printing output |
| Browse the SYSLOG and OPERLOG | ISFLOG | Browsing the system log with ISFLOG |
| Issue system commands | ISFSLASH | Issuing system commands with ISFSLASH |
| Issue SDSF commands for filtering and options, and check messages | Special REXX variables | Using special variables to invoke SDSF function |
| Drop specified special variables | ISFRESET() | Dropping special variables with ISFRESET |
| Query the environment | ISFQUERY() | Invoking a REXX exec with an action character |
| Invoke an exec with an action character | % action character | Invoking a REXX exec with an action character |
| Generate a REXX exec for the current panel | RGEN command | Generating an exec using RGEN |
For examples of REXX execs, refer to Examples of REXX execs.
You must be authorized to use SDSF with REXX and you must be authorized to the SDSF functions that you invoke from REXX. In some cases, invoking an SDSF function from REXX when you are not authorized to the function will cause the exec to fail and the invocation of SDSF to end.
System programmers should be sure to define ISFPARMS group membership so that SDSF users have the proper authorization when invoking SDSF with REXX. For more information, see Security and REXX
