The SAVE statement has two alternative forms:
SAVE item, item, ... item
SAVE
Where each item can be a local variable or (unsubscripted) array, or the name of a common block enclosed in slashes. The second form, with no list of items, saves all the allowable items in the program unit. This form should not be used in any program unit which uses a common block unless all common blocks used in that program unit are also used in the main program or saved in every program unit in which it appears. The SAVE statement can be used in the main program unit (so that it could be packaged with other specifications in an INCLUDE file) but has no effect.
