Abnormal Compiler Behavior ?

Guys,

I was working on writing few completely free programs and stumbled upon this. Despite my prototype and file fields matching it kept complaining about the parameter mismatch for 2nd and 3rd parm.

Dcl-Pr SalaryCalc Packed(15:2);
Grade Char(1);
Level Zoned(1);
#Exp Zoned(2);
End-Pr;


Dcl-PI *N Packed(15:2);
Grade Char(1);
Level Zoned(1);
#Exp Zoned(2);
End-PI;

Definition in file:

A ELEVEL 1S 0
A EEXP 2S 0


I had to change the Level and #EXP field to packed and it compiled fine.

Am I missing this.
