My shell script is executing i am having no syntax errors or other errors. When i am testing the shell script i am having a problem that the procedure Prompt, Environment,List are not found.
I defined all these procedures in the shell script.
Environment()
{
FULL=N export FULL
LOGON=cat | grep ....... etc
.....
}

Prompt(), List()
{
echo Enter the Action here
read action
}

After all these definitions at the botton i am calling these for my use

Environment
case $1 in
-p) Prompt; shift 1;;

but when testing i am getting err: Prompt not found
List not found, Environment not found
