If you have used repetitive INDEX and SUBSTR functions to determine how many times a “word” occurs in a character string, that task can also be accomplished more easily in Version 9. The COUNT function determines the number of times argument 2 occurs in argument 1. ...
The following SAS program filters data where the first two characters of the 'name' variable are 'DA' or 'da'. TheSUBSTRfunction is used to extract the first two characters of the name variable, and theUPCASEfunction converts them to uppercase so that we can select both 'DA' and 'da...
SUBSTR ( character variable, starting point to begin reading the variable, number of characters to read from the starting point) There are two basic applications of the SUBSTR function: RIGHT SIDE APPLICATION data _null_; phone='(312) 555-1212'; area_cd=substr(phone, 2, 3); put area_...
