Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Geoff designed a simple 2 x 16 lcd display and runs it with a bit of code lcd.bas. In line 20 he has LCD_Line1$ = " HELLO WORLD " and line 30 is similar.
It displays it on the lcd nicely.
I'm designing a clock (don't ask) and I have hh$ equal to hours, mm$ equal to minutes and ss$ equal to seconds. I don't want to change Geoff's LCD code.
How can I plug my hh$ mm$ ss$ into line 20 so that it will eventually display
hh:mm:ss in the first line.
Thanks for your help

Try this.

LCD_Line1$=hh$+":"+mm$+":"+ss$

You can add strings together.

Hope this helps.

Thanks Captainbill!
That worked beautifully! I wasn't aware of adding the +
Now I'm going to really push the friendship. When I reach single digits I need to add leading zeros on the display. Can this be implimented in this setup?
I can send all of my code if you want it.

Try this.

if len(hh$)=1 then hh$="0"+hh$

Spot on. It works!
Thanks for your help.
I just need Geoff to impliment his serial in so that I can use a gps NMEA string and the PPS to run my super accurate clock.
