No, he was talking about the userfile and groupfile function, not reading from files.
[userfile ascii2bin ...] and [groupfile ascii2bin ...]

Could easily be done by:
userfile open "someuser"
userfile lock
set newufile ""
lappend newufile "credits 0 0 0 0 0 0 0 0 0 0"
lappend newufile "tagline Unknown"
userfile ascii2bin [join $newufile "\n"]
userfile unlock
ioFTPD would then replace the 'credits' and 'tagline' portion of the userfile with the new values, leaving the rest as it previously was.
