BUG: Linking P-Code with /w Option Gives L4000 Warnings

The information in this article applies to:

   The Linker (LINK.EXE), included with:
    - Microsoft C/C++ for MS-DOS, version 7.0
    - Microsoft Visual C++ for Windows, versions 1.0

SYMPTOMS

Linking a p-code application with the /w option causes more than 500 warnings if the application was built with Microsoft C/C++ version 7.0 and Visual C++ version 1.0. The warnings are of the form:

   <lib>(wcore.asm): warning L4000: segment displacement included
      near <offset> in segment (null)
   frame segment $$PCD_INTERP, target segment $$PCD_INTERP,
      frame segment 42c

   -or-

   <lib>(wcore.asm): warning L4000: segment displacement included
      near <offset> in segment (null)
   target external '__pcdi_snMac'

CAUSE

The warnings may be caused by an incorrect ASSUME directive in the p- code interpreter source (segment instead of group).

RESOLUTION

After running the Make P-Code utility (MPC) on the resulting executable, it runs without error.
