Be careful how you use errorlevel in the DOS world. You have to think
of the errorlevel as a fence. If the fence is 4 feet high any you can
jump 2 feet, your going to hit the fence. In other words, if the
errorlevel is 4, it is also 3, 2, 1, and 0. The difference is whether
you use "if errorlevel" or "if %errorlevel%". errorlevel by itself is a
threshold whereas %errorlevel% is the exact value as shown below.
H:\>perl -e "exit (4)" # Generates an errorlevel of 4
H:\>echo %errorlevel% # Echos 4
4
H:\>if errorlevel==3 echo yes # Tests the threshold up to 4
yes
H:\>if %errorlevel%==3 echo yes # Tests the exact value of errorlevel.
# doesn't echo no

hello,
in unix world the exit(n) returns the number in to a variable. Is this
the same in the dos/windows world? If so what is the variable and how
can I examine it in dos batch file or in perl.
Thanks.
