The following information is from the Microsoft Macro Assembler
Version 5.10 OS2.DOC file.

OS/2 Call Summary
   The OS/2 calls are listed below. The constant symbols associated
with each group of macros are shown before the listings. The listings
consist of the macro name followed by a one-line description. A second
line shows the arguments expected by the macro. The following symbols
are used to indicate the type of each argument:

    W     Word
    D     Doubleword
    PB    Pointer to byte
    PW    Pointer to word
    PD    Pointer to doubleword
    PZ    Pointer to ASCIIZ string
    PS    Pointer to structure

   If the macro expects the address of a structure as one of its
arguments, the structure will be listed below the argument line. See
the include files for listings of structure fields. The include files
also contain definitions for constants often passed to specific
macros.
   This document makes no attempt to explain the purpose or function
of the OS/2 systems calls. The calls are described in detail in
manuals published separately by Microsoft and in some third-party
books and magazine articles.
