File Information
Description

this little routine is a garbage collector that helps to clean up a messy workspace. it collects those numerous variables (or selected members of them) either from the base's or caller's workspace into a handy structure, where each fieldname represents a variable with its contents set to the variable's value. optionally, it will remove the variable after(!) assignment -or- keep only those that are selected. when called within a function with the option s=gcoll('-caller'); it collects all current variables used within that function; other options and/or patterns apply. look at the accompanying image and type help gcoll at the command prompt for more insights.
