SUBJECT  : Batch File Using Nul Operator
DATE  : 5/24/90
FYI #  : 052490cw
OS VERSION  : All
REVISION  : All
SHELL VERSION  : 2.15C

PROBLEM  : The following batch file example will not execute more than five 
or six times before getting "File creation error." using DOS 3.3.  The batch
file name is TEST.BAT 

@echo off
set > nul
dir > nul
ver > nul
TEST

Apparently the shell doesn't handle the nul operator correctly.  It will 
execute once or twice in a row but if you run the batch file recursively 
it gets the error mentioned above.

SOLUTION  : Use the v3.01 shell.  This shell runs the batch file and 
correctly handles the nul operator without getting an error.
