Thanks for the suggestion; I hadn't considered creating libraries yet, but my HOME is starting to get a pretty good amount of stuff in it. I'll check out D->LIB if it gets too unruly.

Basically, I'm not.

I also have a program called SORTALL that dives into each directory recursively and executes SORTDIR (defined globally in HOME, but some directories provide their own to override sorting). This alphabetizes the vars list, placing all directories first, followed by all programs, then leaves everything else following that unsorted to save execution time. (I'll probably post those programs later today.) In addition, I use local variables wherever possible so they vanish automatically.

Hiding variables is doable, though a little clumsy, and requires a SYSEVAL or a tiny bit of SysRPL. If you have an object with a null-string name (i.e. '') in the current directory, everything sorted after it is not shown in the variables list, or by any command that lists variables (VARS, TVARS, maybe others). They can still be accessed normally by name. A little clever directory sorting lets you hide things this way. I have a directory with user-defined units that hides everything but the 'CST' variable to prompt that they should be used that way, and not directly from the vars menu, lest they be overwritten accidentally with left shift.

I haven't bothered streamlining the hiding process yet, mostly because ORDER doesn't give you a simple way to move things to the end of the list, only the beginning. Perhaps that will give me a project to pass the time today in the hospital.
