It's 8 bytes for the name,
3 for a TTR ("first block")
1 for flags (recently linked vanilla modules seem to have X'2C')
3 per optional TTR (you can have 0 to 3 of them - recently linked vanilla
modules seem to have one - doc says "first block of text")
and a maximum of 31 "user" half words (0-62) for the data field (recently
linked vanilla modules seem to have 12 halfwords for total of 24 bytes -
doc says first byte zeroes, TTR of "note list or scat/trans table" [0 in
sample], one byte of length of that table [0 in sample], 3 bytes "main
storage needed", ...)
