FIX: /Z Switch Gives "Unknown Option" Error in MASM 6.0b (93005)
The information in this article applies to:
- Microsoft Macro Assembler (MASM) 6.0b
This article was previously published under Q93005 SYMPTOMS
When the MASM compatibility driver provided with version 6.0b of the
Microsoft Macro Assembler is called with the /Z command line switch,
the following error occurs:
Unknown option: z. Use /help for list of options
RESOLUTION
Omit the /Z switch from the command line. The /Z switch has no effect.
STATUS
Microsoft has confirmed this to be a problem in MASM version 6.0b.
This problem was corrected in MASM for MS-DOS version 6.1.
MORE INFORMATION
The ML driver invokes the Microsoft Macro Assembler (MASM) versions
6.x. MASM includes the MASM.EXE compatibility driver for backward
compatibility with makefiles written for the MASM driver used in
versions 5.x and earlier.
In MASM versions 5.x, the /Z switch displays on the screen the source
file lines that contain errors. In MASM versions 6.0 and 6.0a, the /Z
option is correctly ignored. However, in version 6.0b, MASM generates
an error in response to this option switch and does not assemble the
file.
