3 unusual facts about Borland Turbo Debugger


Borland Turbo Debugger

Although Borland's Turbo Pascal (TP) had useful single-stepping and conditional breakpoint facilities, the need for a more powerful debugger became apparent when TP started to be used for serious development.

The original 1.0 release of Turbo Debugger for MS-DOS will run under simple MS-DOS emulators (DOSEMU, in an MS-DOS Window in Windows 95, 2000, etc.) The later versions attempt to control the underlying machine in a way not allowed by the host operating system (in which the emulator is running) and therefore do not work.

The last MS-DOS version of TD.EXE, 3.2, does run successfully in the 32-bit Windows XP NTVDM (i.e., in a DOS window, invoked with CMD.EXE), but TD286.EXE and TD386.EXE do not.
