WOW! I would never have found that one, you are truly one of the TCL
gurus out there (you came highly recommended by those I know)

this seemed to have fixed the problem (probably overkill but it was the
best I could think up at the moment:

while {[info exists wordlet] && [string length $wordlet] > 0 &&
![regexp -nocase {[a-z]} [string index $wordlet $beginIndx]]} {
append nonWord [string index $wordlet $beginIndx]
incr beginIndx
}
