hi,
I'm writing a program that is reading input from the keyboard, and I
would like to have the program generate IPLOT plots. When the program
calls iplot, however, the iplot window comes up and then freezes. In
fact, the entire IDL environment is frozen and I have to shut down IDL
in the task manager. I'm running windows XP pro service pack 2, IDL
6.1,
student version.
run this program to see what i mean:
pro dummy
inchar = ''
iplot
read, 'give me your input : ', inchar
end
this doesn't freeze all of idl, but it illustrates the basic problem.
the iplot window comes up but freezes until the user types something in
and hits enter. Inserting a "wait, 10" statement after the iplot
command doesn't help.
any suggestions would be greatly appreciated! thanks,
Mark

it seems like in any program that I write, the interpreter is busy
enough that it blocks any iplot update until the entire program is
finished running. the basic structure of what I'm writing is this:
while quit ne 1 do begin
inchar = get_kbrd(0)
case inchar of
'a': begin
commands...
end
'b': begin
other commands....
end
'c': begin
commands...
iplot, something....
end
end
endwhile
when you hit c, the whole IDL environment locks up.
UPDATE: this morning I had a message from RSI saying that they
reproduced the non-updating iplot window, and they think that this
problem is specific to IDL 6.1
