True, but I assumed the OP needed to close ALL open files because an error occurred, or
you've inserted a STOP statement in your code. Then, when you get tossed back out to the
IDL prompt you do something like:

IDL> close, /all
IDL> retall

although I now prefer the more bull-in-a-china-shop method,

IDL> .reset_session

:o)

So, to the OP, I personally *never* use CLOSE,/ALL in "real" IDL code. Just in the debug
parts.

p.s. Although I hear that HEAP_GC is a favourite of some.... :o)
