How IMOD Variables Are Accessed

REXX provides the PROCEDURE EXPOSE instruction to grant an internal subroutine access to the variables of a caller. The VVALUE() CA-GSS extended function grants an external subroutine access to the variables of its caller. Access is granted at all nesting levels of the calling chain, and variables can be read, updated, and created. An IMOD task can establish a variable pool, which is accessible to all external subroutines.
