"R1." is a statement label, likely referring to a READ statement. Statement labels are used as field qualifiers. For example, if your master and transaction files both contained a PERSONNEL-ID field, Natural wold need to know which one you meant. In "R1./11" the slash is used to separate the label from the index.

You could also qualify using the view name:

Code: Select all

view.UNIT-CONTROL = view.HOLDING-POS-UNITS-HELD(11)

This statement assigns UNIT-CONTROL to the value of the 11th occurrence of HOLDING-POS-UNITS-HELD.
