Hi idl experts
I'm running IDL V5.0.2 WIN32 under WIN95 and I am writing a
widget-based program. At some point my program calls another IDL program
with keywords and parameters stored in local variables. I expected the
program to behave like:
IDL> myDirectory = 'C:\RSI\myData'
IDL>ImageOut, myDirectory
but it won't!
For details see below:
..
If (cpy eq 0) Then Begin
kwd1 = 'HCOPY=0'
..
EndIf Else Begin
kwd1 = 'HCOPY=1'
..
EndElse
;call other idl program (EM.PRO) with keyword now
EM, kwd1
..
The program crashes then with the following message:
IDL>EM_GUI
%EM: Incorrect number of arguments.
%Execution halted at: ...
One of the grizzly facts is that I don't know where the error message is
coming from because in EM.PRO there is no such message implemented!
Help about the keyword reveals the follwing information:
IDL> help, kwd1
KWD1 STRING = 'HCOPY=0'
An hints or suggestions are very much appreciated by
