Despite being atomic values, poke strings can be indexed in order to retrieve individual characters:
(poke) "word"[2] 0x72UB
Note how the indexing is zero-based, i.e. the first position in the
string is referred as [0]
, the second position with [1]
,
and so on.
If you specify a negative index, or an index that is too big, you will get an error:
(poke) "word"[-1] <stdin>:1:8: error: index is out of bounds of string "word"[-1]; ^ (poke) "word"[5] <stdin>:1:8: error: index is out of bounds of string "word"[5]; ^
