[SR-Users] Working with Variables.

[dotnetdub]

Hi List,

Where is the best place to lookup documentation about working with
variables.

I come from the if len(x$)=y then

                                    xxx
                                    xxx
                                    xxx

                        End If


 school!

Looking for the best place to lookup documentation for checking characters,
lengths of strings and removing or prepending stuff based on the results.


Thanks
Brian
