For that you use the Gs function: str_cat( string to pointer, string from pointer) the string from pointer can be like this.. str_cat(str1,"second text added"); to retrieve individual chars, you can use str_trunc and clip, manipulations, though i think there might be a high chance ( i didnt explore yet) about char[char-number] options.

STRING is defined in atypes.h as Code: typedef struct STRING { C_LINK link; char chars; // pointer to null terminated string long length; // allocated length of string long flags; // see STRF_... above byte pad[PAD_STRING]; } STRING; Therefore you must access the character data as (strname.chars)[index]. The first character is index = 0 etc. Just remember that STRING is not the same as char*. Our new web site:Westmarch Studios
