Hello, I want to define an array of constants including the character (,) but does not allow me to do so, is there any way to define this ("CGREG 1.1)?
| Code: | const char Strings[TOTAL_STRINGS][SIZE_COMMAND]={"OK\0", // index 0
"CGREG:1,1\0", // index 1
"+CMTI\0", // index 2
"ERROR\0", // index 3
}; |

You can include any character, by using it's octal or hex value,
So \x2C or \053 generates a comma.

It works for me. I compiled the program shown below in vs. 5.016 and
ran it in MPLAB simulator, and I got the following output. It displays the comma:
Here is the test program:
| Code: |
#include <18F4520.h>
#fuses INTRC_IO, BROWNOUT, PUT, NOWDT
#use delay(clock=4M)
#use rs232(baud=9600, UART1, ERRORS)
#define TOTAL_STRINGS 4
#define SIZE_COMMAND 11
const char Strings[TOTAL_STRINGS][SIZE_COMMAND]=
{"OK\0", // index 0
"CGREG:1,1\0", // index 1
"+CMTI\0", // index 2
"ERROR\0", // index 3
};
//===================================
void main()
{
printf(Strings[1]);
while(1);
} |
Note that the compiler automatically puts a 0x00 byte at the end of each
string (this is part of the definition of a string). You are adding an extra
0x00 on the end of each string, for some unknown reason. So you really
have two zeros at the end of each string. |

I wonder if he is running out of space?.
Doesn't show the declaration for 'SIZE_COMMAND', and with the extra terminators, would need 11 characters for this line.
