How do I copy a string in ROM to Ram?

Hi all. Mcc18 has a function in string.h file called strcpypgm2ram() defined as:

Quote:

char *strcpypgm2ram (auto char *s1, auto const MEM_MODEL rom char *s2);

/** @name strcpyram2pgm
* The {\bf strcpyram2pgm} function performs a {\bf strcpy} where {\bf s1}
* points to program memory and {\bf s2} point to data memory.
* @param s1 pointer to destination in program memory
* @param s2 pointer to source in data memory
*/

In my LCD.c file I am using this function as:

strcpypgm2ram((char *)t_string,version);

where version is : rom const char version[] = "0_00";
and t_string is : unsigned char t_string[12];

How do I do that in CCS?

It's very simple. Use strcpy().

Code:

strcpy(t_string, version);

Thanks I have done that before you reply. I should have reply earlier saying it's ok. Sorry.
