Martin:
Unix IDL 5.3 also has another problem: idlde doesn't handle files greater
than
a few hundred lines in its editor. More lines than that and they just don't
show
up on the screen. Tech support told me they switched to a 3rd party
chroma-color-enabled editor in 5.3. They did not tell me when to expect
a fix.
