the archive "bin3r4p2-ibm-i386-dos.zoo" from May 18th of length 230578
bytes on ftp.math.rwth-aachen.de contained a corrupted GAP binary for
MS-DOS in which the help function didn't work.
I have replaced the archive with a new one. The new archive is from
May 30th and 230994 bytes long. The source code is not affected, so
you can either ftp the new executable or create a working GAP
executable by recompiling GAP using DJGPP and the source code
distributed in "gap3r4p2.zoo".
sorry for any inconvenience
