Tips Talk:Counting Words in a List
good tip! --Nancy 12:45, 18 June 2009 (UTC)
Good TIP, good instruction w/good examples; Looks complete. Charlie Shipp 15:24, 19 June 2009 (UTC)
Nice tip - ready to go! --Phil Miller (STATPROF) 17:26, 26 June 2009 (UTC)
Countw does not count words delimited by just blanks. See the example below. -- chang_y_chung 21:50, 14 January 2011 (UTC)
%macro countw(list=); %sysfunc(countw(&list)) %mend countw; %macro count(list=); %eval(%sysfunc(count(%cmpres(&list),%str( )))+1) %mend count; %let critters=wolverines/grizzles moose; %put countw=%countw(list=&critters); %put count=%count(list=&critters); %*-- on log countw=3 count=2 --*;
These two also behave differently (and incorrectly) when a null string is passed.
%let critters=; %put countw=%countw(list=&critters); %put count=%count(list=&critters); %*-- on log ERROR: The function COUNTW referenced ... countw=. count=1 --*;
- A tip should really convey just one idea. This one is not about word-counting per se, but rather about "borrowing" these functions for use in a macro. It is already on the long side; perhaps it should illustrate only COUNTW.--Howles 23:49, 26 January 2011 (UTC)
- Perhaps there should be an article about the various word-counting functions, compared and contrasted. I would only favor that if the relevant documentation is weak, or hard to find. I think this wiki should try hard to avoid mission creep.--Howles 23:49, 26 January 2011 (UTC)
