Purge All variables of Eq Lib (HP50)

[Joe Horn]

Long answer: The Equation Library has a built-in utility for this. After you select a subject and title, press the [VARS] soft key (not the VAR key) to see a list of the variables and their meaning. Press [NXT] and see the soft key [PURG]. When that soft menu key is pressed, All the variables used in the current equation are purged from the current directory.

Short answer: [VARS] [NXT] [PURG].

Alternate method: When you press the [VAR] key (below the [APPS] key), your vars are listed in chronological order, newest first. So just press [VAR] then an open list bracket { and then the menu keys to type their names into the list. Stop when you reach your programs, because you'll recognize their names, if you gave them good names. Then press ENTER and PURGE the list.
