COUNTW Function

Counts the number of words in a character string.

The following example shows how to use the COUNTW function with the M and P modifiers.

options ls=64 pageno=1 nodate; data test;    length default blanks mp 8;    input string $char60.;    default = countw(string);    blanks = countw(string, ' ');    mp = countw(string, 'mp');    datalines; The quick brown fox jumps over the lazy dog.         Leading blanks 2+2=4 /unix/path/names/use/slashes \Windows\Path\Names\Use\Backslashes ; run;  proc print noobs data=test; run;
