&B00+x contains the offset with &B00 to the start of string x
&B01+x contains the offset with &B00 to after the end of string x
 
So, on a BBC:
soft key string 0 runs from &B00+?&B00 to &B00+?&B01-1.
soft key string 1 runs from &B00+?&B01 to &B00+?&B02-1.
soft key string 2 runs from &B00+?&B02 to &B00+?&B03-1.
...etc... up to
soft key string 15 runs from &B00+?&B0F to &B00+?&B10-1.
