In the REXX language, all variables are local, and only within PROCEDUREs are variables local (private), except |
|||
<br>for those identified via the EXPOSE option. There is a variant where the EXPOSE can have a list specified. |
|||
<br>Any REXX variables in an external routine (program) aren't known. |
|||
<br>There is a mechanism that allows external programs to access local REXX variables and is essentially restricted to |
|||
<br>assembler programs that use the REXXAPI interface. |
