What is Fortran 14 output?

Question

I am writing a javascript lexer/parser for DXF files and have come across this from the AutoDesk Drawing Interchange and File Formats document:

The first line of a group is a group code, which is a positive nonzero integer output in FORTRAN I3--that is, right-justified and blank filled in a three-character field (the exception to this is the four-digit extended entity data group codes, which are output in FORTRAN I4).

This clearly states what FORTRAN 13 output is, but what is FORTRAN 14 output? A Google search returns absolutely nothing. It must be similar to FORTRAN 13 in style, but how big is the field?

What is FORTRAN 14?

Probably I3 and I4 (leading character is a letter, not a digit). That is a fortran format specification for a formatted integer in three character or four character width field respectively. — IanH, Jul 11 '14 at 09:01
I see. That makes perfect sense. Alan from IRC provided this [link](http://www.cs.mtu.edu/~shene/COURSES/cs201/NOTES/chap05/INT-out.html) — oorst, Jul 11 '14 at 10:16
@TimChild I edited the question back, except of the citation. Your edited completely changed the meaning of it. It was useful for people with the same confusion as the original asker. — Vladimir F Героям слава, Oct 25 '14 at 08:20
@VladimirF The author asked 'but what is FORTRAN 14 output?' This make no sense in the context on FORTRAN output codes. 'FORTRAN I4 output' makes perfect sense as a DXF group code is an integer. — Tim Child, Oct 27 '14 at 15:22
@TimChild Yes, the author was confused. Write an answers that clears his confusion. Do not change the fundamental meaning of the question! — Vladimir F Героям слава, Oct 27 '14 at 15:24

The documentation mentions I4, not 14. The Fortran output format I4 stands for an integer with width four characters.
