PRB: L1035 Linking MOVE Application Using a Fastcall Function

• Microsoft LINK for MS-DOS, versions 5.3, 5.31, 5.5, 5.6

SYMPTOMS

An attempt to link an application fails and Microsoft LINK generates the following error message:

fatal error L1035: syntax error in module-definition file

CAUSE

The application is using MOVE overlays and has a function that uses the fastcall calling convention in an overlay. The name of the function is specified in the module-definition (.DEF) file, with the preceding @ character.

RESOLUTION

Enclose the name of the function in the module-definition (.DEF) file in double quotes ("").

MORE INFORMATION

The following sample code can be used to reproduce the problem:

Sample Code
