Hi everyone,

I used two procedures, 'read_jpeg.pro' and 'read_png.pro', both of
them worked well. After a disruption (in dead loop), I closed the
terminal and resulted in fault. After I restarted another session, it
complaint my procedures

IDL> read_jpeg,'img1.jpg',img1
% Attempt to call undefined procedure/function: 'READ_JPEG'.
IDL> tmp=read_png('img.png')
% Compiled module: READ_PNG.
% Attempt to call undefined procedure/function: 'READ_PNG'.

Any one knows what might be the problem? they both worked well before
the fault.

Cheers
