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
variables 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
variable(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 values to a same register variable in more than one object will result in an error in
linking process.
