It may have been a bug in the v2.00 version.  Before I answered your
question I looked into the library source code for rand() and srand()
(in src/libc/ansi/stdlib/rand.c if you must know).  The seed value for
the randomizer is a static global variable, which means it is _always_
initialized to zero when your program is run.  I cannot think of any way
in which v2.00 could have handled the coding without initializing to
zero, unless it ran srand() by default in startup (a kludgy solution).

Randomize() is non-ANSI and was not ported from Borland, as equivalent
functions already exist.  ;)
