50g User RPL crasher (don't do this!)

[ettlz]

I don't know if this is known, and I know it's a bit too late for a firmware update, but still. This is a an HP50-C rev. 2.15. If you do this, back up first -- this corrupts the memory on mine.

I was playing with 'naked' lambdas in User RPL.

Code:

{ -> a << a 2 + >> } OBJ-> DROP 'func' STO

Next try to edit func.

Code:

'func' [ENTER] [LEFT-SHIFT] [DOWN]

It'll open up, press [ENTER] again and an error will flash briefly. Next pop anything onto the stack -- a number will do.

Watch the screen fill with garbage until the 'Try to recover?' prompt appears. Oops!
