Regex aficionados would want to emphasise that 

replace entry = regexm(text, "^\([E|N|Y][0-9]") if entry == 0
replace entry = regexm(text, "^[E|N|Y][0-9]") if entry == 0

is equivalent to

replace entry = regexm(text, "^\(*[E|N|Y][0-9]") if entry == 0

Note that the code segment I gave is tailored to the document you specified. But the small tricks in using functions may well still be useful for other documents. BTW, I tried copy and paste first, but that failed for some reason.

That was what i thought.
The best way to go is prob to find the ICD lists i need online, use your
infile suggestion and then merge the two data sets.
Thank you.
