Thanks for the reply Ron.
I am purely doing this to learn different way's of basically doing the same thing.
I have made several routines to read and print out a GPS string array but I would like to learn how to change the degrees and minutes e.c.t with my own code and this seems to be the best example for me to learn from.
It seems that you have hit the nail on the head with the HEX modifier.
I have not tried it as yet but I am sure that this is what I need to know.
I have never done math with HEX characters so I am interested to learn.
I will hit the search button and find some references to HEX math examples as it looks puzzling to me at first glance. I need to get it right in my head before going any further.
Ron I am the sort of bloke that likes to make simple things difficult and then further simplify them in order to learn. Being self taught - for me this is reasoning !!!!!!
Thank you for taking the time to reply Ron.
