SAS array define error

%let ng = 4;

data a1;
set a2;
array cur{&ng} cur1-cur&ng.;
do i = 1 to &ng.;
if (_n_ = (i-1)*5 + 1) then cur[i] = Val; 
end;
run;

Error msg

ERROR: Missing numeric suffix on a numbered variable list (cur1-cur).
ERROR: Too few variables defined for the dimension(s) specified for the array cur.

ERROR 22-322: Syntax error, expecting one of the following: a name, (, ;, _ALL_, _CHARACTER_, _CHAR_, _NUMERIC_.  

ERROR 200-322: The symbol is not recognized and will be ignored.

Why do i = 1 to &ng. and cur{&ng} work but cur1-cur&ng. generates errors?

That code works fine for me, however I have encountered this problem where I've created a macro variable (in this case ng) with the proc sql into: or call symput methods, as these set a default length of 8 and pad the value with spaces. I suspect in your actual code the macro variable ng is being created in one of these ways.

To get around this, try adding %trim as below.

array cur[&ng.] cur1-cur%trim(&ng.);

You also need to add an end statement to close the do loop.
