+ Final routines in doscalls implemented. * Fixed bugs in dos.pas. * Changed some old $ifdef FPK into $ifdef FPC. - Removed go32 stuff from dos.pas. - Removed '/' to '\' translation from system unit - EMX does this automatically.

|
|
{This unit was called bsedos in the original OS/2 runtime library.
|
|
Changed, because it's an interface library to DOSCALLS.DLL.
|
|
|
|
The goal was to make this unit a real Pascal unit instead of a C unit in
|
|
Pascal clothes. Not that I want to make every translated statement look
|
|
exactly like other Pascal code, but in this case, it was too crazy.
|
|
Therefore typenames, constants etc. have names like the ones in IBM's
|
|
documentation (which is C oriented), but do not match exactly. In general
|
|
constants do now use the common two letter prefix, followed by the constant
|
|
description. Type names use a capital T in front of their name, handles do
|
|
not have separate types, longints are used, and whenever possible pointers
|
|
were replaced by var parameters. All constructions like 'type LONG=longint'
|
|
have been removed. Furthermore, most of the procedures also accept strings
|
|
instead of just a Pchar, thanks to that cool feature of procedure
|
|
overloading.

Coding style:
|
|
|
|
It may be well possible that coding style feels a bit strange to you.
|
|
Nevertheless I friendly ask you to try to make your changes not look all
|
|
too different. To make life easier, set your IDE to use tab characters,
|
|
turn optimal fill, autoindent and backspace unindents on and set a
|
|
tabsize of 4.}
