Relabelling programs

[Marcio]

Create the following program on the 35s:

Code:

X001 LBL X
X002 4
X003 +
X004 GTO X002

XEQ the program, relabel it W and then XEQ it again. The 35s will not update the GTO instruction, which is understandable, but the problem is that it won't read or recognize the new label, the display will show NONEXISTENT. For this to happen, there must be a GTO instruction in the program. Later on, for some reason I cannot explain, the 35s will recognize the program exists.

Is this an oddity or a bug?

Note that if you attempt to reproduce this, step X003 is necessary to avoid the lockup bug, which will cause all programs and data to be lost!!

Thanks
