How to Run Rexx on Your Mac (5/2008). A perennial favorite is the rexxcps program. This script measures how many Rexx clauses per second your machine executes. So the command succinctly lists all files in the directory. Running a Rexx Program. The ooRexx interpreter is invoked by the command, rexx. 4 ways to execute REXX codes. One question is should I execute the CONCAT command each time I log into mainframes? Write a jcl step to execute the tso program IKJEFT01. REXX Instructions Provided by NetView. These functions are provided as part of the NetView program so that command lists written in REXX can perform. The American Programmer: Home. This is what you can do so that you will be able to execute your REXX program on MVS TSO/ISPF. Then execute it this way from the command line of any ISPF panel. REXX Instructions Provided by Net. View. Because these instructions are provided by. Net. View and are not standard REXX instructions, they can be used only in. Net. View environment. These instructions do. REXX EXECs that are running in non- Net. View. environments. The REXX instructions provided by the Net. View program can. To handle error conditions, code the SIGNAL instruction in. REXX command list that uses one of these Net. View instructions. This list includes. Net. View and instructions provided by. TRAP and WAIT. instructions. When a TRAP instruction is issued, Net. View begins. monitoring the operator task for an occurrence of a specified message. The command list can then take action based on. Nested REXX command lists can also contain a TRAP. However, trapped messages are available only to the. TRAP instruction. Therefore, TRAP commands issued from. It is possible, therefore, for the message queue to grow large. The first REXX program and How to. If the system admin does not allow running a REXX/CLIST, then execute the following. When the program finishes running, it returns control back to REXX. The program/command also returns some numeric value that REXX automatically assigns to the variable. They often execute faster than issuing a shell command. REXXTRY invokes the REXX code as a command and does not set &RESULT.to execute an in-line REXX. The return-code produced by the REXXTRY program is the return-code received from. Net. View to run out of storage. The following. considerations apply when using WAIT with nested command lists. Messages that arrive for the waiting command list are queued until the. If you use the REXX CALL instruction to. If you invoke a nested command list. CALL instruction, trapped messages are available only to the. TRAP instruction. The functions.

DSI0. 08. I SPAN1 NOT ACTIVE. The functions are set as follows. Variable. Value. MSGORIGN(). SPAN1 NOT ACTIVE. MSGVAR(4)- MSGVAR(3. The value of MSGCNT() is 0. The. MSGVAR(n) functions retain any values they are given when the command. The value of MSGCNT() is zero. Refer to the GETM commands in the Tivoli Net. View for OS/3. 90 Command Reference for information concerning working with multiline messages. If MSGVAR(1)- MSGVAR(3. MSGREAD instruction. This lets you use the values that. MSGREAD. These functions are provided as part of the. Net. View program so that command lists written in REXX can perform specific. Net. View activities. Because these functions are provided by Net. View and. are not standard REXX functions, you can use them only in command lists that. Net. View environment. These functions do not execute in any. REXX execs that are run in non- Net. View environments. If the same function. Net. View, is used several times in the command list without a. You can then use the local variable in. If the value returned by the function might. To use a function, you must place the function name in the. REXX command list at the location where you want the information to be. When the command list runs, Net. View returns the current value. This list includes. Net. View and functions provided by REXX. KR 2. 28: Executing REXX codes. KR- 2. 28* How to execute REXX codes. Addendum to the REXX crash course series. REXX codes 1.) Foreground execution. Prefix member name by EXEC within. Another foreground method. Type TSO EXEC 'pds(rexx- member)'. Foreground again (most. To run. the rexx exec without giving specifying the path we can allocate the PDS containing. REXX member to SYSEXEC or SYSPROC - > these are the files that are searched. Usually. SYSPROC contains all user created CLISTS; so we can append our dataset to this (SYSPROC. ISRDDN command. to check datasets allocated in your session. To allocate. datasets to SYSPROC use the following TSO command: CONCAT FILE(SYSPROC) DA('pds. SHR REUSE Now. if your REXX code is called CREATOR then you can just say TSO CREATOR on any screen. We can. also say: %CREATOR One question is should I execute. CONCAT command each time I log into mainframes? Another option is that your mainframe. CONCAT step to this file. Running a REXX exec in. Write a jcl step to execute the tso. IKJEFT0. 1. In the SYSTSIN card we can give the. TSO commands to be executed. Ex: //SYSTSIN DD * EX 'TEST. SS. REXX. EXEC(CREATOR)'. If you want to pass arguments to your. SYSTSIN DD * %CREATOR arg. CREATOR code should then have an ARG statement to capture the arguments).
