This mail contains a bugfix for a dangerous problem in GAP 3.4.3.
*You should apply this bugfix as soon as possible if you are using
the facility to convert character tables to MOC format*.
The problem is in 'PrintToMOC', and causes it to print code that
may be misinterpreted by MOC 3.

HOW TO APPLY

The problem is a dangerous problem, because it causes MOC to deal with
corrupted data if the argument of 'PrintToMOC' contains numbers with more
than four digits. Thus the bugfix has high priority, and we recommend
that you apply it as soon as possible if you are using 'PrintToMOC'.

Go to the GAP directory (the directory with the 'lib/' subdirectory),
name this mail 'bugfix14.dif', and issue the command:

patch -p0 < bugfix14.dif

If 'patch' writes "I can't seem to find a patch in there" try 'patch -v'.
If 'patch -v' gives an error message or reports a version older than 2.1,
get 2.1 from 'ftp://FTP.Math.RWTH-Aachen.DE/pub/gap/utils/patch2_1.zoo'.

This workaround changes only the library.
Thus you need not recompile the GAP kernel.

VERSION

GAP 3.4.3.0

DESCRIPTION

The local function 'PrintNumber' omits the middle two of the last four
digits of numbers with more than four decimal digits, so (in the example
below) instead of 'v0625' the string 'v05' is printed, which is not valid
MOC 3 code.

CORRECT BEHAVIOUR

gap> t := CharTable( "A5" );;
gap> chi := List( t.irreducibles[5], x -> x^8 );;
gap> moctbl := MOCTable( t );;
gap> PrintToMOC( moctbl, [ chi ] );
