Besides, how many sheets of paper do you have laying around with 1987 dates marked "**** HONEYWELL FEDERAL SYSTEMS INC. CONFIDENTIAL and PROPRIETARY ****"? This dates to when I was on the SCOMP team, though has nothing SCOMP-related or even remotely confidential or proprietary. What was SCOMP? See http://en.wikipedia.org/wiki/Multilevel_security
So I scanned the code with xsane and noticed, as I had before, the option to save as text. As before, it didn't work, but this time I paid attention to the error message, gocr not found. So I googled and then install gocr (see http://jocr.sourceforge.net/) .
gocr does a respectable job, but not great. However, it's better than typing from scratch. Here are some lines from the scanned text:
- l2 jnclude stdio.h>
l3 include <signal.h>
15 #define ALL_USEn_PROCS -l
l7 void main()
l9 int kill();
20 jnt process_id;
21 int signal;
23 process id = ALL USR PROCS;
24 signa! =- SIGKTL ; -
25 void rintf(''\nkil1ing all rocesses...\n'');
26 void ill(prOcess_id, signa );
So it's missing underscores, curly brackets, and various other things. It looks like it added line numbers, but that's from the paper listing. Not great, but it beats typing that code from scratch, I guess. There may be some options that help it do a better job, so if this becomes important I'll have a look.
