Can someone help me understand the structure of XML a little bit more ? Specifically, in the IF / ELS structure can you have another IF / ELS structure within it ? It seems like you can't have an ELS within a larger IF / ELS construct, but I'm thinking you can have multiple and if statement within one.
Also when it comes to the command (S0:, etc) 'subroutines', is there an equivalent 'return' command once the subroutine finishes, or is it automatically returned back to the original routine just after the S0: command was run ? Does it return at all ?
