Fortran::Format version 0.90
============================
This is a Perl implementation of the Fortran 77 formatted input/output
facility. One possible use is for producing input files for old Fortran
programs, making sure that their column-oriented records are rigorously
correct. Fortran formats may also have some advantages over C<printf> in some
cases: it is very easy to output an array, reusing the format as needed; and
the syntax for repeated columns is more concise. Unlike C<printf>, for good or
ill, Fortran-formatted fields B<never> exceed their desired width. For
example, compare
printf "%3d", 12345; # prints "12345"
print Fortran::Format->new("I3")->write(12345); # prints "***"
This implementation was written in pure Perl, with portability and correctness
in mind. It implements the full ANSI standard for Fortran 77 Formats (or at
least it should). It was not written with speed in mind, so if you need to
process millions of records it may not be what you need.
CHANGES SINCE VERSON 0.54
- Added reading support! (some bugs may be lurking there)
- INCOMPATIBLE CHANGE: matrices will be transposed on writing;
non-rectangular nested arrays result in undefined behavior.
- Fixed bug where 2(I8),I2 would reuse only the 2(I8) on subsequent
lines instead of reusing the whole format string.
