I have a problem of running this program (I am newbie in IDL...:
When I run this prog (compiles OK) it should when I press the
'dismis'-button remove the value in the textfield named 'a0'. But I get
always the error:
"pointer type required in this context"
can somebody give some help ?
regards
taejon

Some examples would be:
curve = [0,1,2,3,4]
curve = 3*findgen(10)^2.0
curve = sin(findgen(100)*!pi/180.)
(or whatever values your curve wants to take)

Dear
How i can define a variable in the IDL for example define CURVE. I will be appreciate to helping me. Thank you

IDL is not Python. It only executes statements (ex:
"something=something_else"), procedures (ex:
"some_procedure,some_argument"), or commands (ex: ".continue"). If you
just type in the command line a variable name, it will assume you are
calling a procedure with that name. If you want to know about a
variable, you need to use some command. For instance:
print,some_variable
help,some_variable
print,n_elements(some_variable)
print,size(some_variable)
etc.

That error means that the code thinks that 'curve' is a function, not a variable. Check it is defined as a variable, e.g. curve=[0,1,2,3,4,5] or similar, and check how you are referring to it in your code (i.e. that you're not calling it like a procedure/function).

Dear Andy
for example i wrote the curve in the command line i found this message.
curve
% Attempt to call undefined procedure/function: 'CURVE'.
% Error occurred at: $MAIN$
% Execution halted at: $MAIN$
I can not understand the meaning of this experession. Could you help me about this. Thank you

I'd check that your variable 'curve' is defined and an array. The error message suggests it is not.
Hope this helps,
Andy

hi Dave,
Are you using idlde ?
Those directories are created when you first launch a new workbench (from idlde).
The .metadata can't be removed because it contain's all the preferences of the used workbench.
For the "Default" normally if you erase it from the IDE it won't appear after.
if you are not using idlde you may launch idlde just to erase the "Default" dir.
