string functions

[Gerrit Faas]

Hello All,

I just used some string functions in my code. It's anoying
that you can't used pointers to constants.

Is there some one how has some library (and want to share)
where part of these problems are solved.



Regards,

Gerrit

This is an overview from an example published by Peter H. Anderson. This can be purchased.

In program ROM_1.C this technique is used to initialize a string and, display the string at run time. In program
ROM_2.C (not shown in this discussion), this is extended such that multiple strings are stored in a continuous
memory area. To display the nth string, the program traverses the memory counting the number of ‘\0’
characters. That is to display string 2, the program traverses the memory until it has found two ‘\0’ characters
corresponding to string 0 and string 1, and then fetches the characters until the ‘\0’ character associated with
string 2 is found.

This is probably the most compact method of storing strings with a PIC18 series.
