Thank you for your help.
I compiled all the procedures related to readfits and writefits.
When I run readfits, it gives this error:
Attempt to call undefined procedure/function: 'READFITS'.
Execution halted at: $MAIN$
As a result, the files cannot be read when they are called:
files=['test1.fits','test2.fits',...] ; I tried files_search it does
not work.
writefits work when is run.
What could I do?
