I'm trying to write a somewhat generic menu handler in ARexx on the Amiga. My Do_Menu.rexx file originally started with /* do_menu */ Do_Menu: procedure parse arg a b blah blah if recurse; then call Do_Menu(a, b) Now the recursion is required and thus some kind of procedure is required. However, on first call from a separate file, "procedure" gives an error. So I changed it to /* do_menu */ signal enter Do_Menu: procedure enter: blah blah This seems to work. However, I now want to expose some variables in order that the results of the menu functions can have some effect on the caller. Basically, the Do_Menu function reads and INTERPRETs strings from a file. I want INTERPRET to be able to change the values of variables (as well as look at variables) from the caller. The ideal mechanism would be passing in a string containing a list of root symbols that would be exposed. I tried INTERPRET 'procedure expose' varlist but that does not seem to work. Any help here, no matter how kludgey, would be appriciated. How do I get to the caller's variables from a separate-file ARexx macro called from ARexx? -- Darren
