PROCDESC         Define procedure prototype                         Directive

  PROCDESC procname [procedure_description] ; Ideal mode
  procname PROCDESC [procedure_description] ; MASM mode

    Declares a procedure prototype, which lets Turbo Assembler check the
    types and number of parameters to procedure calls and declarations, and
    specifies language and distance. Also serves to PUBLIC or EXTRN the
    procedure.

    Be sure that PROCDESC appears before the PROC declaration and any use
    of the procedure name.

    Example:    PROCDESC ptest pascal FAR :word, :dword, :word
                ; ...
                call ptest pascal, ax, ds bx, cx    ; OK
                call ptest, ax, ds bx, cx           ; OK (language default)
                call ptest C, ax, ds bx, cx         ; Wrong language
                call ptest pascal, eax, ebx, cl     ; Wrong parameter type
                call ptest pascal, ax, ds bx        ; Too few parameters

                Note: The PROCDESC declaration generates the following
                      statements:
                      PROCTYPE @Type_PTEST PASCAL FAR:WORD,:DWORD,:BYTE
                      GLOBAL PTEST:@Type_PTEST

                Note: Overriding the language specifier in a CALL to an
                      external procedure has no effect, but will generate
                      a warning only if the module is assembled with the
                      /l or /la switch (!?).
