array question

deleted_user — Thu, 15 May 2008 19:19:49 GMT

Any idea what is wrong with this code?

array region{22} region_1 - region_22;
array ais{22} ais_1 - ais_22;
array trhead{22} trhead1-trhead22;
do i = 1 to dim(ais) ;
if region(i)='HEAD' then do trhead(i)=ais(i); end;
-
73
ERROR: The variable type of trhead is invalid in this context.
ERROR: Illegal reference to the array trhead.
ERROR 73-322: Expecting an =.

325 end;

missing semi-colon after the "then do"
Should be "then do;"

It's syntax errors like this that I waste HOURS on ! Lol.

I was taught that rule 1 of SAS programming is "Where is the semicolon?"

I counsel people to reread their code and ensure that all between their semicolons is valid SAS code. I can't count the number of times that going back to rule 1 has allowed me to find an error in my own code.

That's my 8 farthings worth.

Kind regards
