From the code I'd say: ( y mat -> r )
Where mat is a matrix descriptor and y is the element you search.

x[<->] Y
m_find_loop:: x=?[->]Y
JMP m_found
ISG Y
JMP m_find_loop

Thank you.
I don't understand r.
For 5,6,7,8 stored in registers 20 to 23
stack y: 55 x: 20.0401 returns 24.02301
and
stack y: 7 x: 20.0401 returns 22.02301
Presumably the second result indicates "found"? How should this result be interpreted?
Thank you.

You probably want the index of the element. The matrix descriptor is still in the last x register. Therefore you can use:
For 7 you get (x, y) = (3, 1). For 55 you get an Error: Out of range.

Thank you & yes that is the info I needed.
Will now get to work on Shanks SQFF.
