Searching literals

[malena]

I am doing literal searches for several variables for specific terms.

One of these variables contains a description of up to 100 terms. So I am doing a search on this variable for a specific term: One of these terms is "OD". But I do not want to count them if the terms are "probable OD" or "suspected OD".

I am using these 2 functions: findw and index, are these any other better functions to use?

thanks!

Please show example, using a starting SAS data set, and the desired result.

PRXMATCH, which is regular expressions. They're incredibly powerful for searching text strings.
