HP50g - Can't Factory Reset & What's this?

[BartDB]

There is a workaroud for the IFTE bug, a bit more verbose but you can use IF...THEN...ELSE...END

For example code that gives the IFTE error:

Code:

«
 'IFTE(X<1,X,X^2)' STEQ
 ERASE -3 3 XRNG -10 10 YRNG
 DRAX DRAW PICTURE
»

This one will not error and draw the required graph:

Code:

«
 « IF X 1 < THEN X ELSE X SQ END » STEQ
 ERASE -3 3 XRNG -10 10 YRNG
 DRAX DRAW PICTURE
