Help implementing "goto <label>" in korn shell script....

[Guest_imported]

Hello,

I am looking for help with a korn shell script. Basically, I am trying to implement &quot;goto <label>&quot; in my script, so that if I supply a command line argument to my script, I can jump to that position. For example:

<Myscript.ksh>
echo This is the beginning of the script
End:
echo This is the end of the script

I would like to execute the command:
Myscript.ksh End

and have it jump to the end of the script (or some other position defined by my labels) when executing. However, all of my efforts seem to indicate that neither &quot;goto&quot; or the use of labels is supported in the version of korn shell I am implementing. If anyone else has any ideas of a good way to do this, or knows what I am doing wrong, that would be a big help.

Thanks in advance

Mike

I don't think ksh supports gotos - perhaps you could try csh?

That said, I seem to recall something about a way to get ksh to imitate a goto somewhere in the unix threads - have you tried a search for goto in them?

HTH.

goto bad ...very bad....bad goto...


use a loop with a case statment in it.

while true
do

case $1
label1)dosomething;change $1;export $1;;
label2);;
exit)break;;
*);;
esac
done

then manipulate the value in $1


...my 2 cents

There was a similar question in Thread80-72438 , which seems to have concluded that functions are the way to go(to). Good luck.

goto's are horrible. Try to work with
functions in the script and call the function
when you want to goto somewhere.
