Retrieve data from a data area and use it in a project

There are two sets of code here, one for a CL program that will retrieve a value from a data area and place that value into a variable, the second is the XML for a project that will call the program and retrieve the value stored in the variable.

Code: Select all

           PGM PARM(&value)

 @ENDPGM:                                                              
           ENDPGM

<project name="Retrieve value from DataArea" mainModule="Main" version="1.0">
	<module name="Main">

</project>

You will, of course, need to make changes to fit your situation.
