In reviewing inherited code I come across:
var1 =COMPRESS(var1, '');
I've looked at the Compress documentation and several examples, but not sure what the two single quotes with nothing in them does?
thx
As a minimum it would remove blanks from the variable which would likely only be easily noticeable if they were leading or imbedded in the variable.
Examine what happens here:
data junk;
var1 = ' some name ';
var1 = compress(var1,'');
put var1;
run;

perfect - that's what I thought but wanted to ensure it wasn't doing ADDITIONAL formatting...gonna remove the quotes so they don't confuse the next bloke
