Two procedures for Discrete Cosine Transform,
translated from C by Robin Vowels, and using PL/I's scaled FIXED BINARY
for fast binary fixed point arithmetic.
Greg Price (gprice@ozemail.com.au) offers the "Worm" program, which runs in
an OS/2 (DOS-type) window under OS/2. You'll need to type MODE 80,33 prior
to execution, which will give 33 lines on the screen.
Download and run the Worm executable program. Worm PL/I source.
