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.
