" hELLO" OUTPUT in forth give hELLO at the screen.
Now I will use this OUTPUT (of long string incl ESC characters for Video command ) instead of EMIT of single characters. I suppose the speed will be better. Result in few days.

(11-15-2023 04:43 PM)J-F Garnier Wrote: A third (and intermediate) way is to use the OUTPUT statement:
OUTPUT :1 ;"HELLO!";
that should do the same thing.

It does, same messages in the same order. Thanks!

I made a rework by avoiding the EMIT word which extensive looping is making the output slow.
By creating string buffers then using the word OUTPUT (probably similar in BASIC; see previous exchanges), it looks better (weird interferences in EMU71 are not seen anymore). Thanks for all supportive hints in this thread.

The result is a mix of further actions for a smooth update:
- string buffers with maximum 255 char long
- only the necessary number will be updated (frame draw one time; draw of HH MM SS only after check this is necessary)
- no date update check (if you keep it running 1 week, only the time will change)

The test on an hardware is still open (all test in EMU71 and Video80 done).

So far working.. (Linux 64bits PC starting windows binaries from ILPER ILVIDEO80 EMU71)

Clock in Video80 with EMU71 and Forth.

a) install timeasm
b) install HP71B1 and CLOCK; see below
c) start with STARTCLO: you have now a good looking clock (fonts mostly from Sylvain Cote proposal)
d) EXIT with pressing the key E

This was worked out on a cross-development based on gforth. Presentation of details planned so far for Allschwill 2024. An additional layer for retranscription of HP71B word into gforth words was necessary (subject still in development; so far all float, integer, string words retranscriptions available).

UPDATE 29Nov2023. When using the HP71B hardware (and ILPER and VIDEO), initialize the variable PRIMARY to zero with 0 PRIMARY ! (else it will put the data into the corresponding device like printer or others which are in the loop)
