Thank you! Bug filed:

I am fine changing 'tExt'. As Martin just posted, ‘All words in the 
English Dictionary should be considered reserved words.’ is not a bad 
rule. Just to illustrate how the eyes and mind can play tricks, I have 
been using the variable 'tExt' for parsing file extensions for DECADES 
and ONLY TODAY realized that it was the word 'text'! I never saw it as a 
dictionary word until today!
