(C4099) Textual subroutines using uninitialized local variables

Error In:
Completeness
Description:
Local variables of a textual subroutines are used before they are affected or assigned a value.
Format:
<local variable name> in <subroutine name>
Example:
Subroutine F1 is defined to be a function with input parameter X that returns an integer Y and has two local variables (A and B) defined:
A=B;
B=X+3;
Y=B;
return(Y)
 
In this case, B is used before it is initialized.
