In what way do your second line not work? The $ctrl in your posted example code have 8 spaces char(32), and $ctrlNonMissing will have 6 spaces. stritrim() trims char(32) only, if you have other space characters in your string:

global ctrlNonMissing = ustrregexra("$ctrl", "\s+", char(32))

Oh, sorry, this works. I made a mistake here.
