6.2.39.7.1 Values at the End of Execution of the UNSTRING Statement
The following operations are performed only once, at the beginning of the
execution of the UNSTRING statement:
- Calculations of subscripts, reference modifications, variable-lengths,
variable locations
- Evaluations of functions
Therefore, if identifier-4, identifier-5, identifier-6, identifier-7, or
identifier-8 is used as a subscript, reference-modifier, or function
argument in the UNSTRING statement, or affects the length or location of
any of the identifiers in the UNSTRING statement, then these values are
determined at the beginning of the UNSTRING statement, and are not
affected by any results of the UNSTRING statement.
