@echo off
echo Test DOS batch file
if "%1" == "" goto help
goto end
echo You must enter a command line parameter.
echo You entered %1.

#in bash labels (functions) need to come before use

help() {
echo "You must enter a command line parameter"
if [ "$1" = "" ]; then  help
else echo "you entered $1"

Note that functions are not quite like goto.  The function returns when
it is done.  Put exit at the end of your function if you don't want

However, the same thing in a more bashy way:

if [ "$1" = "" ]; then
echo You must enter a command line parameter
else echo You entered $1
