4.7.2 Variable Format Expressions

Fortran 77 allowed any integer constant in a format to be replaced by an arbitrary expression enclosed in angle brackets:

1 FORMAT( … < expr > … )

Variable format expressions cannot appear as the n in an nH… edit descriptor, in a FORMAT statement that is referenced by an ASSIGN statement, or in a FORMAT statement within a parallel region.

This feature is enabled natively in f95, and does not require the -f77 compatibility option flag.
