Hi guys,

Please give me some direction with this one

Re: string manipulation

you would get a lot more help if you explain what microcdontroller you are using, and the language you are programming in (asm, c)

the best way would be to buffer the string in ram, then check each byte.

use pointer to manuplate them........ it will give u more contol it is more faster
btw compiller put '0' after every string by it self to indicate string is end.

Re: string manipulation

Include <string.h> and use the functions that come with the standard c libraries.

ts work fine if you are dealing with limmited length of string, and data is not manuplating in multiple fuction but for the other case u have to use pointer
