Hi,

if I create a matrix in Free42 and edit it in the Matrix editor, I get the edited matrix in X (correct) and a 0 (zero) in Y, which I think is incorrect.
(Free42 2.5.21, Windows.)

Stack before matrix editor:
T: 1
Z: 2
Y: 3
X: [ 2x2 Matrix]

After matrix editor:
T: 2
Z: 3
Y: 0
X: [ 2x2 Matrix]

IMO this should be:
T: 1
Z: 2
Y: 3
X: [ 2x2 Matrix]

Or did I overlook something?

Same behaviour as in the 42S I’m afraid.
The first element you enter will push the 0 to Y, and there it stays till you EXIT the editor.

Yep. The stack lift behavior in the HP-42S matrix editor is a bit odd. Buggy, even. And Free42 emulates this behavior, in order to avoid introducing incompatibilities that might break programs that depend on the original behavior.

See the release notes, for releases 2.0.18, 2.0.19, and 2.0.20.

Hello Werner & Thomas,

thank you for the information!
