z/OS Rexx Executor - Usage

---

The z/OS Rexx Executor plug-in will execute statements provided in a dataset or inline in the plugin step.

Select Source type as DATASET from the drop-down and enter the dataset in the Source Value. Fully qualified dataset needs to be enclosed in single quotes. When the quotes are omitted then, the TSO prefix of the id running the plugin step is prefixed to the Source Dataset.

(or)

Select Source type as INLINE from the drop-down and then in the Source Value enter REXX statements beginning with a /* REXX */ statement.

Arguments can be passed to the REXX program with/without quotes. However, if there are more than one argument then arguments must be separated by a space.

The SYSPROC field allows user to pass datasets containing REXX programs that will be used by the REXX program run by the plugin step. Multiple SYSPROC datasets can be passed by separating datasets by a comma(,).

Setting output property

This plugin allows user to set output properties from the REXX program and later to be used in successive steps of a process. A user REXX program can simply invoke a call to SETPROP with two arguments.

The first argument is output property name and the second argument is the property value.

CALL SETPROP propertyName propertyValue

For example, below REXX snippet will set an output property currentDate with value of date variable

---

/* REXX */
date = DATE('S')  /* Returns date in YYYYMMDD format E.g., 20120327 */
CALL SETPROP "currentDate" date   

Setting multi-line output property

To set a multi-line output property, the lines of the property value must be separated by a delimiter returned by inbuilt program GETDLMTR

---

/* REXX */
delimiter = GETDLMTR() /* Return delimiter to separate lines */
lines = "This is first line" || delimiter || "This is second line"  
CALL SETPROP "outputLines" lines

Will set property outputLines to below value

---

This is first line
This is second line

Referring properties from successive steps

If the rexx step name is Run-Rexx-Program and output property name is currentDate then the output properties can be referred by the successive steps as below

${p:Run-Rexx-Program/currentDate}

Note

From plugin version 2, an output property RexxReturnCode will store the return/exit code from REXX program.
