Flag toggling

Hi,

I found a little two-command sequence to toggle a flag (in this
case it is flag 01) each time the code is executed without any
further register or variable involved:

FC?C 01
FS 01

...may be it is useful in some cases...

Cheers!

Re: How to enter a right pointing triangle into a string in prgm mode?

hI,

yes, it is that character...but I want to insert it into a string of a program.
While in programming mode I have no curren stack / current X-value
from which I can XTOA (see my initial posting).

menu item.
Since the triangle is not bound to a key sequence (right ?) I am unsure
how to enter tjis in program mode.

How can I do this?

Cheers!
