Hi,

with Thomas' Free42 there is a nice feature:
When "printing" a code listing to the internal thermo paper there is an arrow on the
left hand side of each "LBL"-intruction. This makes reading of code much easier - especially when
following instructions like XEQ and GTO.

When listing code with the DM42 there is no such marking.
If an additional marking of lines, which contain a LBL instructions would considerably slow down scrolling I would think that not
diplaying line numbers for those lines will increase readability the same way.
Since lines will follow the n->n+1 scheme, I think the loss of
informations in that case will be very acceptable in the context of the increased readability you will get in turn.

What do you think?

OK, so how would you mark the currently active program line? That's what the arrow is for in PRGM mode (on the DM42, Free42 and the HP-42S). It does appear against a LBL in struction on a paper listing just as it does for the HP-42S, for that matter.

How about inverting?

Hi,

for the currently editable line use the arrow (as it is already done).
For marking "LBL-lines" remove the line counter on the very left.
Or use any other character in the space between line numbering and code.
An "X" for example would be visible enough I think.
Should not be too complicated.
Only drawback would be a -- possible -- impact to the scrolling speed.
In that case -- as said -- the removal of the line number would do the trick,
I think.

Is it really a problem as it is now?

All of these changes proposed mean fundamental changes to Free42.
