QPATH by Douglas Boling
PURPOSE:
A small TSR (Terminate and Stay Resident) utility that directs DOS
to begin its search for a command with a given path rather than with the
current directory, and which prevents DOS from executing specified commands.
FORMAT:
QPATH [/D][/E][/U][/X cmd[, ...]]
REMARKS:
Entering QPATH at the command prompt installs the utility, which
requires slightly more than 1K of RAM. On 386 and 486 machines, QPATH may
be loaded in high memory by using the LOADHIGH command of DOS 5.0 or the
equivalent command of memory managers such as 386MAX. The DOS SET command
is used to assign the string indicating the path to be initially searched
to the environment variable QPATH. The path string can be changed from the
DOS prompt at any time.
The optional /X switch precedes one or more commands, separated by
commas, which are to be disabled. To change the list of such commands
requires uninstalling and reinstalling QPATH. If desired, a command with
the same name as the one that is excluded from execution can be run via
a DOSKEY macro or by specifying the full path with the command.
The /D switch may be used to disable QPATH, restoring normal DOS
operation. The /E switch will enable QPATH once again. If no TSRs that
use Interrupts 21h or 2Fh have been loaded after QPATH's installation,
QPATH can be uninstalled by using the /U switch. QPATH requires DOS 3.3
or later; it is known to be incompatible with DESQview.
