Example: char

In the following example, each element in an array of char's, character_set, is converted to lower case.

    char character_set[] = {'A', '5', '$', 'Z'};
    int i;
    for (i=0; i<4; i++ )
        lr_output_message ("%c", tolower(character_set[i]));
Output:
Action.c(7): a
Action.c(7): 5
Action.c(7): $
Action.c(7): z
