st: RE: String Problem
You do not say what constitutes pain, but I will guess from your example that it is the presence of the character sequence "D4" anywhere in the code variable.
In that case, the pain variable can be created with a single string function:
gen byte pain = strpos(code,"D4")>0
gen byte pain = strmatch(code,"*D4*")
(In Stata 8, replace strpos() with index() and strmatch() with match())
Hope this helps

I have the following string variable code and would like to create the variable pain. Code is a combination of two digit codes (1 letter,1 number) lumped together as many 6 codes can be combined.
code pain Z1D4 1 Y1 0 H4T2D4F7 1 D4D5 1
I am not sure what combination of string functions to use. Can anyone help?
