"delay" is standart library function for Turbo-C, but not for MSC.
Some "delay" emulation code for MSC in file "dcplib.c" contains very
unplesant bug:
...
milliseconds =- (t.millitm - last); /* Yes --> mSecond delta*/
...
milliseconds =- 1000 * (int) (t.time - seconds)
...
But in MSC (like in all ANSI's standard compilers) "=-" means "= -",
not "-=". I spend more then 6 hours to localize this bug.

I spend more then 6 hours to localize this bug. and the bloody thing loops forever. I fixed that ... I thought. I know the system hung on me when testing it. Only took me an hour, but *I* knew what I had changed. The next release will use DosSleep instead. I hope to get the OS/2 version done soon, which requires use of the MS C compiler; hence the next release will be tested better ... I hope.
