Question:

I cannot seem to get the /CPARMAXALLOC linker option to work when I
link for OS/2 protected mode. When linking a real-mode application, it
works correctly. Also, when I type "link /help" in protected mode, the
output indicates that this is a valid option. However, when I try to
use this option for a protected-mode application, the linker produces
the following warning:

   LINK : warning L4013: invalid option for new-format executable file
                         ignored

What am I doing wrong and what does this error message mean?

Response:

As documented on Page 27 in the update section of the Microsoft C
Optimizing Compiler Version 5.10 "CodeView and Utilities, Microsoft
Editor, Mixed-Language Programming Guide" manual, the /CPARMAXALLOC
option is for real-mode applications only. The "link /help" indicates
that this is a valid option because this option IS valid whenever
you're linking real-mode applications, regardless of whether the
linker is running under OS/2 or DOS. (By the same token, it is invalid
when you're linking a protected-mode application, regardless of which
operating system you're using.)

This error message was omitted from the documentation. It indicates
that one of the options that the linker was passed is invalid.

This option is not supported in a protected-mode application because
the functionality of it is done automatically by the linker.
Protected-mode applications are not given a 64K default data segment;
they are only allocated the space that they need. This is documented
on Page 33 of the same section and manual listed above.
