6.2.39.3 POINTER Phrase
When the POINTER phrase is specified, the value of the pointer field behaves as if it were increased by 1 for each examined character in the sending field. When execution of the UNSTRING statement is completed, the pointer field contains a value equal to its initial value, plus the number of characters examined in the sending field.
When this phrase is specified, the user must initialize identifier-7 before execution of the UNSTRING statement begins.
- identifier-7
-
Is the pointer field. This field contains a value that indicates a
relative position in the sending field.
Identifier-7 must be an integer data item defined without the symbol P in the PICTURE string.
It must be described as a data item of sufficient size to contain a value equal to 1 plus the size of the data item referenced by identifier-1.
X When identifier-1 (the sending field) is a DBCS data item,
X identifier-7 indicates the relative DBCS character position (not the
X relative byte position) in the sending field.
