HP41C CLOCK EMULATION ON THE HP71B I quite liked the idea of having my 41C on my desk with the clock displayed, ready for instant use. I was able to duplicate this CLKTD display of the 41C on my 71B which has LEX files with the keywords KEYWAIT$ and CLOCK as follows: DATE$ @ CLOCK ON @ PUT(KEYWAIT$) @ CLOCK OFF The use of PUT (suggested by Graham Fraser) duplicates a keystroke so that with the clock in the display, as on the 41C, any keystroke clears the display (note: ATTN will leave the CLOCK on, clearing only the date. gf.) and performs its normal operation. I assigned this tiny routine to a key (as a colon definition) so that I can turn it on any time I have finished a task and also included it in my STARTUP string: SFLAG -9 @ PUT "defined key" (SFLAG -9 ensures USER mode on) The only thing I am not sure of is: Does the high power state of CLOCK nullify the low power state of KEYWAIT$????
