Node:Turbo Pascal compatibility, Next:Supported platforms, Previous:Current version, Up:GNU Pascal
GPC is not a drop-in replacement for Borland's Turbo Pascal (R).
Almost all BP language features are supported. Notable exceptions
are the string format (as discussed below), or the Mem and
Port pseudo arrays, though replacement functions for the
latter on IA32 platforms exist in the Ports unit.
Almost all of BP's run time library is supported in GPC, either by built-in compiler features or in units with the same names as their BP counterparts.
For details about the compatibility, the few remaining
incompatibilities and some useful alternatives to BP features, see
the Borland Pascal chapter in the GPC Manual.
