Field Global Storage


Storing Data by Position within a Node

If you want to store a field's data by character position within the Global node, rather than by ^-piece position. This is called extract storage instead of ^-piece storage. To accomplish this, after specifying a subscript, respond to the ^-piece prompt with Em,n; where m is the first character position for data storage and n is the last. For example, to store data in character positions 1 to 3 of subscript 20, do the following:

Figure 389: Field Global Storage—Storing Data by Position within a Node

    SUBSCRIPT: 20
    ^-PIECE POSITION: E1,3

One advantage of specifying your field data location using the Em,n format is that caret (^) can be part of the stored data. It is recommended that you do not mix extract and ^-piece storage on the same Global node.
