Hi! I am a beginner on iraf script.I am writing a script that would input a .fit image file then rspectext the image file to an IRAF image spectra and at last splot the output iraf spectra. And my script look like this:

procedure askchan
string input
string output
begin
string image10, image20
image10=input ; rspectext(image10)=output
splot(output)
end
But when I try running the script I keep having errors, can somebody help?

rspectext(image10)=output

This is an invalid statement, I think you meant

image20=output
rspectext(image20)

You didn't say what error you were seeing specifically. Since the task has parameters (i.e. anything declared between the 'procedure' and the 'begin') you'll need to declare the task as

cl> task askchan = /path/askchan.cl

If you want the input/output parameter to be supplied on the command line you'll need to declare them as part of the procedure statement,i.e.

procedure askchan (input, output)

Be sure to load the ONEDSPEC package before you run your script.
