Yes, I was surprised as well, since the xTalk languages I'd been using
didn't have them either and the other languages (VB included) did, so I was
hoping that MetaCard (this was before it became Revolution) would have it.

However I must admit I've had to craft a few functions for VB that I was
surprised *it* didn't have one-liners for as well, so I guess it kind of
goes both ways.

Actually, if they implemented it, it'd probably be more syntactically
correct as:

  put LTrim(myVar1,space,numToChar(202),numToChar(160)) into myVar2
  put Trim(myVar1,space) into field "Label1"

but either way, it would be very beneficial to have them. Bob, if you've
used Bugzilla or RevZilla before, perhaps you can log those in as requested
enhancements? If you haven't used them, let me know offlist and I'll log the
enhancements for you.
