How do you convert a string variable to lower case? Say, you have a string with the value ''My String''. How do you convert it to ''my string''? There seems to be a ToLower Function, but I can't see how to use that properly? Any suggestions would be appreciated.

Try this:

scn testfunctionshort asciicodestring_var inputstring_var outputstring_var characterBegin Function {input}	let output := ""	while (index < sv_length input)		let character := input[index]		let asciicode := CharToASCII character		let asciicode := ToLower asciicode		let output := sv_Construct "%z%a" output asciicode		let index += 1	loop		SetFunctionValue $outputEnd

Seems to be working now thanks.
