Sorry, there is no further description I can give you. tclsh locks,
produces 100% CPU usage when you view via top, no error logs of any
kind.
Here is PROPER_CASE:
[TCL]
#######################################################################################
#
# Proc PROPER_CASE - this proc will convert string text into "marquee"
style
# by displaying its "proper case" (or in this case: "Proper Case").
The
# first letter of each word is capitalized except for small words
(yet,
# small words are capitalized if they are the first word in the text).
# Special capitalization consideration is taken for common ethnic
words,
# hyphenated words, and words adjoined by underscores. Also
consideration is
# taken for words surrounded by non-alphabetic characters (updated
7/10/2000)
#
# UPDATE 11/21/00: Exemptions within the phrase are now accepted
within
# PROPER_CASE to allow for words within phrases to not be capitalized.
#
# SYNTAX: set myPhrase [PROPER_CASE $myPhrase] {for all words}
# set myPhrase [PROPER_CASE -exempt [list of exempted words]
-- $myPhrase]
#
# IMPORTANT: If you include a list of words to be exempted you MUST
include the
# following:
#
# -exempt : This flag indicates an exemption list is to
follow
# -- : End of exemption list
#
# Without including "-exempt" before your exemption list
there will be no
# words to exempt; without including "--" it cannot deduce
the end of the
# exemption list and this proc will return an empty string.
