HS_getAns |
Function (ROM Call 0x241) |
Returns the handle of a Home Screen answer.
HS_getAns returns a handle to the answer part of the Home Screen history pair with
index Index, where Index is a value between 1 and 99 and has
the same meaning as the parameter of the TI-Basic 'ans'
pseudo-function.
If the answer does not exist, HS_getAns returns H_NULL.
This happens in three conditions
- The entry/answer pair does not exist.
- The answer is a message like "Done" that comes after an executed program.
- The answer is an error message (i.e. ERROR_MSG_TAG is present in it).
The returned handle contains a "multi-expression"; see
MULTI_EXPR and
HS_getEntry for more info.
