There are 15 GOSUBs in Akalabeth.
They go to:
- 100 (two times)
- 200
- 500 (four times)
- 2000
- 4000
And the three we've already seen:
- 60000
- 60080 (three times)
- 60200 (two times)
There are only 8 RETURNs. They are at:
- 190 (return for 100 although it's possible to start at 90)
- 490 (return for 200 although line 491 should form part of this section too)
- 590 (return for 500)
- 2090 (return for 2000)
- 4999 (return for 4000)
- 60075 (return for 60000)
- 60130 (return for 60080)
- 60210 (60200 actually goes until 60250 but that last line is a go to back to 60210 which returns if the player quits from the shop)
Other code sections not covered by this:
- 1000–1700
- 3087–3089
- 6000–6060 (player death)
- 7000–7990 (Lord British's Castle, including quest bestowal, quest hand-in and game completion)
