The information in this article applies to:
- Microsoft Macro Assembler (MASM), version 6.1
-------------------------------------------------------------------------------
SYMPTOMS
========
An attempt to run the Microsoft Macro Assembler (MASM) version 6.1 fails and
MASM generates the following message:
Phar Lap err 58: Can't create VM swap file of size 0 in directory
This error does not occur when MASM runs in an MS-DOS window in Microsoft
Windows.
CAUSE
=====
MASM is installed on a read-only drive, possibly a network drive. The error
occurs because the DOSXNT DOS extender attempts to create a virtual memory swap
file on the drive DOSXNT runs from when the operating system does not support
virtual memory.
RESOLUTION
==========
To work around this problem, you can run DOSXNT on a read/write drive listed in
your PATH MS-DOS environment variable. In addition, you can specify one of the
following two environment variable settings to prevent DOSXNT from attempting to
create a swap file on the read-only network drive:
- Set the DOSX environment variable to prevent DOSXNT from using any virtual
memory. Edit your AUTOEXEC.BAT file to include the following:
set dosx=-novm
- Set the DOSX environment variable to specify where DOSXNT creates the virtual
memory swap file. Edit your AUTOEXEC.BAT file to include the following:
set dosx=-swapdir <path>
where <path> specifies the drive and directory on which to create the
temporary swap file.
STATUS
======
Microsoft has confirmed this to be a problem in MASM version 6.1. This problem
was corrected in MASM version 6.1a.
