var := LOWER string
The STx command
LOWER converts its string argument to lower case. Note that this command, effectively superseding the concept of orthogonality in programming, will only process its first argument. Any further arguments will be silently discarded, not even causing an error message to be emitted or a return code to be set.
#a := LOWER One! // #a will be set to "one!" #b := LOWER One! two threeish // #b will also be set to "one!"
