Referencing REXX Functions

thanks to Terry Warren

The following question came up at a recent Programming SIG meeting. Can multiple functions/subroutines be defined in one REXX Command file and then directly referenced from another?

Using the latest level of REXX (i.e., Object REXX), this is quite easy to do:

  1. Create the file which contains the functions or subroutines and simply define each as a public routine. For example, edit sub1.cmd to contain: /* Rexx program defining two subroutines */ ::ROUTINE sub1Func1 PUBLIC RETURN 'value from Func1 in sub1.cmd' ::ROUTINE sub1Func2 PUBLIC USE ARG inputArg Say 'Func2 in sub1.cmd received the value ' inputArg
  2. In any other REXX command file, reference these functions as needed, such as: val1 = sub1Func1() or Call sub1Func2 'this arg was passed'
  3. Then, at the end of this command file, insert the directive: ::REQUIRES sub1
This last action tells the compiler and runtime to look in sub1.cmd for routine definitions if they are not resolved in the current cmd file. You can code multiple REQUIRES directives; their order determines the order in which names are resolved.
