Additional Explanation for Statements
Effective range of labels
Labels are effective only in a file.
Definition of common variables (by
COMMON statement)
In an object to be executed first (that is, in a main object), you should define all common vari-
ables to be accessed. In any other objects, declare common variables required only in each
object. If a first executed object is linked with an object where an undefined common vari-
able(s) is newly defined, then an error will result.
Definition and initialization of register variables (by
DEFREG statement)
As for work variables, you should declare required register variables in each object. You may
specify an initial value to a register variable in each object; however, giving different initial val-
ues to a same register variable in more than one object will result in an error in linking process.
