Just a bit more info (I already posted "lexical" is my algorithm.
I did an "amtape DS1 inventory". It lists all 240 tapes.
The output has two values in the last column, "[retention-tapes]"
and "[retention-no]". However these do not match the in-use vs.
skipped tapes.
DS1-000 to DS1-009 [retention-no] # recreated after crash
# currently being skipped
DS1-010 to DS1-018 [retention-tapes] # most recently used
# after looping from 207
DS1-019 to DS1-077 [retention-no] # oldest used and I assume
# will be used next
DS1-078 to DS1-207 [retention-tapes] # used after 077 and
# looped to 010
DS1-208 to DS1-239 [retention-no] # newly created, never used
# skipped over
