SYMPTOMS
========

When you are working in an MS-DOS Prompt session within Windows 95 or when you
boot Windows 95 to a command line, command lines are limited to no more than 127
characters.

CAUSE
=====

The default command-line character limitation is 127 characters. In this default
configuration, the MS-DOS environment does not allow more than 127 characters to
exist in a given command line.

RESOLUTION
==========

The global command-line character limitation can be increased to its maximum by
placing the following line in the CONFIG.SYS file:

  shell=c:\windows\command.com /u:250 /p

This command affects all MS-DOS virtual machines (VMs) as well as the Windows 95
command line.

NOTE: If the SHELL command is already present with the /u switch, increase the
value to 250.

MORE INFORMATION
================

With the command-line character limitation set to its maximum, filenames are
limited to 250 characters minus the number of characters in the command line.
For example, if the command line reads

  copy con "<long filename>"

the maximum length of <long filename> is 244 characters (that is, 250 minus
the 11 characters of the command line).

NOTE: It is necessary to put the filename in quotation marks only if the filename
contains special characters (such as spaces).
