CA's Programmer's Guide To ARexx provides sample sourcecode for a function library. The first step would be to create a library with the same name as the library of interest prefixed by rp – for example rpmylib.library for mylib.library. The function list needs to be modified to include all the function names in the library of interest. You can use a program such as Strings to extract the function names from the original library. Finally, you modify the dispatcher to return a boolean to indicate whether a function exists in the table. RexxPlus takes the boolean as indicator to code a direct reference to the target library at compile time. Note that you want to return the boolean instead of actually calling a function as that would require you to provide a stub for each name in the function table. With a little preplanning, you should be able to place thefunction list in a separate module so that you could easily create an rplibrary by linking in the function table of interest. This would be handy if you plan to do a number of these. Bob
