EXIT in wp34s Message #1 Posted by Jeff O. on 18 May 2011, 3:53 p.m.
I seem to recall some discussion of the EXIT command, possibly with regard to exiting menus and such. If the following discussion is repetitious or the answers can be found in the manual, please accept my apologies. I looked (possibly too briefly) through the manual and found the following information regarding the EXIT function:
Mode Remarks
Catalog Open Leaves the catalog without executing anything.
Input Pending Cancels the execution of pending operations, returning
to the calculator status as it was before.
\PRG & pro- Stops the running program like R/S below.
gram running
PRG Leaves programming mode like h-P/R below.
Else Does nothing
In several cases it seems that EXIT returns the program pointer to step 000.
Based on my usage, I observe the following behavior:
Mode Remarks
Catalog Open Leaves the catalog without executing anything.
Input Pending Cancels the execution of pending operations, returning
to the calculator status as it was before except returns
program pointer to step 000.
\PRG & pro- Stops the running program like R/S below.
gram running
PRG Leaves programming mode like h-P/R below except returns
program pointer to step 000.
Else Returns program pointer to step 000.
Also when used as the ON key (i.e., pressing EXIT when the calculator is off) it turns the calculator on and returns the program pointer to step 000.
If the above is correct, I would like to propose that EXIT only return the program pointer to step 000 in the "Else" case above, i.e.:
Mode Remarks
Catalog Open Leaves the catalog without executing anything.
Input Pending Cancels the execution of pending operations, returning
to the calculator status as it was before.
\PRG & pro- Stops the running program like R/S below.
gram running
PRG Leaves programming mode like h-P/R below.
Else Returns program pointer to step 000.
Included in the above request is that when turning the calculator on, it comes on with the program pointer where it was when it was turned off, although it is OK with me to leave programming mode if the calculator was turned off in programming mode.
