Re: Informix compiler parsing is poor

Has anyone else noticed this? Absolutely, the most infuriating is when simple syntax errors generate broken code like the print statement you mentioned. I ran into the problem that if I closed a window that I hadn't opened (I mis-typed the name) the executable would core dump. Why can't the compiler catch this? ---- Martin Andrews andrewm@ccfadm.eeg.ccf.org Dept. of Neurology Phone (216)444-7485 Cleveland Clinic Foundation Fax (216)445-6617
