Operation	Operands	F mode, L mode
@CONVERT	[ [ { lines | svars } [,...] ] TO = ] { UPPER | LOWER }

lines	One or more line ranges in which conversion is to be performed. Only existing lines are processed.
svars	One or more ranges of string variables in which conversion is to be performed.
UPPER LOWER	All lowercase characters are converted into uppercase. All uppercase characters are converted into lowercase.

Either UPPER or LOWER must be specified. If neither lines nor svars is specified then conversion is performed throughout the entire current work file.
