The Turbo Pascal 3 family included three compilers:
* TURBO.COM, the standard compiler;
* TURBO-87.COM for compiling programs that would only run on a computer with an x87 math co-processor;
* TURBOBCD.COM that included a binary coded decimal (BCD) data type for highly accurate real numbers.
Initially, the latter two were additional products and had to be purchased separately. At 3.02A, all three compilers were included in the package.
Yes, I still have my 3.01A & 3.02A diskettes with manuals and will keep them 'til the day I die.
