array question

deleted_user — Thu, 15 May 2008 19:20:39 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;
-

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;

My first guess would be that the array region is defined as numeric.

replace array region{22} region_1 - region_22;
array region{22} $ region_1 - region_22;

See what happens.

Good idea, but it didn't help.

448 array region{22} $ region_1 - region_22;
449 array ais{22} ais_1 - ais_22;
450 array trhead{22} trhead1-trhead22;
451 do i = 1 to 22 ;
452 if region(i)='HEAD' then do trhead(i)=ais(i); end;

I think I meant trhead but try to define them all as character

The second ones should be numeric, but it still isn't working. Thanks for your help. I'm calling tech support.

513 array region{22} $ region_1 - region_22;
514 array ais{22} $ ais_1 - ais_22;
515 array trhead{22} $ trhead1-trhead22;
516 do i = 1 to 22 ;
517 if region(i)='HEAD' then do trhead(i)=ais(i); end;

You need a semi-colon after the do

replace if region(i)='HEAD' then do trhead(i)=ais(i); end;
with
if region(i)='HEAD' then do; trhead(i)=ais(i); end;
