Hi,
I have a string and I want to remove last word with length one or two.
Example 1: Input: EXPERTS INTERNATIONAL RECRUITMENT S --------Output: EXPERTS INTERNATIONAL RECRUITMENT
Example 2: Input: LOOTAH BUILDING CONSTRUCTION LL -----------Output: LOOTAH BUILDING CONSTRUCTION
Please help.
In below code the RegEx for want1 just removes the last term, the RegEx for want2 only removes the last term if it has 1 or 2 characters.
data sample;
infile datalines truncover;
input have $80.;
length want1 want2 $80;
want1=prxchange('s/\b\w+$//',1,strip(have));
want2=prxchange('s/\b\w{1,2}$//',1,strip(have));
datalines;
EXPERTS INTERNATIONAL RECRUITMENT S
LOOTAH BUILDING CONSTRUCTION LL
LOOTAH BUILDING CONSTRUCTION LLS
;
proc print data=sample;
run;
If the last word is longer than two chars it should not be removed, right?
Are words separated by blanks only?
If both assumptions are true, then i would use:

You could simply scan the last word by space, and check if length is 1 or 2:
data want;
str="abc ert werty we";
if lengthn(scan(str,-1," ")) in (1,2) then check=1;
run;
