Big stack and Σ+

Post by pica »

I believe that I have found a small bug relating to big stack and the Σ+.
The 42s has the great facility of allowing the user to put all their data into an Nx2 matrix, and enter it all at once with Σ+.
I use this frequently, as I can then check my data before doing the Σ+.
If I am in big stack mode, and have only an Nx2 matrix in the stack, Σ+ fails with error "Too few Arguments".
To replicate:

Create say a 3x2 matrix with random data

Code: Select all

NSTK
STO DATA
CLΣ
CLSTK
RCL DATA
Σ+
Σ+ clearly does not like to find a stack with only one level.
If the stack has just two levels, Σ+ works.

Its nothing that I can't live with, but it does not seem right.
I have had to add a 4STK command as the first line to many of my programs, but mostly this is because of the way in which I have used the stack.
This seems to be a glitch, but it does not stop the DM42 from being a most amazing machine.

Testing WP43S, C43.

Confirmed! That's a bug.
I'll fix it in the next release.
