An Introduction to SAS Character Functions

Overview SAS software is especially rich in its assortment of functions that deal with character data. This class of functions is sometimes called STRING functions. With over 30 new character functions in SAS 9, the power of SAS to manipulate character data is even more impressive. Some of the functions discussed in this paper are: LENGTH, SUBSTR, COMPBL, COMPRESS, VERIFY, INPUT, PUT, TRANWRD, SCAN, TRIM, UPCASE, LOWCASE, (concatenation), INDEX, INDEXC, AND SPEDIS. Some of the new and exciting SAS 9 functions that will be covered are the "ANY' and "NOT" functions, the concatenation functions (and call routines), COMPARE, INDEXW, LENGTHC, PROPCASE, STRIP, COUNT, and COUNTC.
