Using A Goto Label?

Im trying to do something like this but I cant find any documentation.

Code:
read X
if [ $X = 1 ]
then goto ThisLine
fi

OTHER CODE
OTHER CODE

Label: ThisLine  echo "You entered 1"

you can use the goto statement in Csh but other shells like ksh,sh (not supported).

You can create function and call the function.

Code:
#!/bin/sh

ThisLine() {
    echo "You entered 1"
    return 0
    echo "I wasn't executed because on the return command :("
}

read X
if [ $X = 1 ]; then
    ThisLine
    echo 'Done!'
fi

exit 0

Here is an example on your code using a function instead of a goto
function needs to be created before the main code, else you get ./script.sh: 6: ThisLine: not found
return is optional if it is placed at the end of the function
you can put an argument after the return, defining the exit status of the function
