TURBO PASCAL

A commercial program was available in the days of MS-DOS 2.11 which did eliminate needless routines from a compiled program created by TURBO PASCAL. This decreased the .COM file accordingly because the entire Run Time Library1 is linked into any compiled program. I planned to perform this for CP/M, too2 . But it led to disassembling of the complete compiler. I also added some new functions as well as procedures. But not only because of these reasons but also due to some missing functions in the CP/M implementation of TURBO PASCAL I started disassembling. E.g. the function „APPEND" was missing which was easy to code. The JOYCE allowed to find out the current cursor position (WHEREX, WHEREY) easily. Also I like the DU: specification describing files. At last I rewrote the editor for best utilisation of the JOYCE keyboard.

After assembling the modules a new version of the compiler will be generated using the CP/M PLUS linker by:

LINK TPnew=TR,TM,TEN,TC,TI[A]

Original source TURBO.MAC.

Stimulated by the work of disassembling TURBO PASCAL I composed a TURBO PASCAL compiler which may be invoked by a command line like usual CP/M programs.
