7 | /* A program to compare two files line by line. | |
8 | ||
9 | History: | |
10 | ||
11 | It was originally written in C, but the C under | |
12 | Panos is still a shambles (1986). Translated therefore | |
13 | to BCPL -- this explains some of the odd style. | |
14 | ||
15 | Modified to run on Archimedes, August 1987. | |
16 | Modified to run under MSDOS, March 1989. | |
17 | Modified to run under CINTERP interpreter, July 1989. | |
18 | Modified to run under Unix, October 1989. | |
19 | ||
20 | Translated back into C, March 1990! */ | |
