| Array define... |

Hi
Now I'm confused, how to define this array correct, it's only a demo for my problem?
| Code: | | const char AString[?][?]={"12","1234","123","1","12345678"}; |
I can put a little more information:
| Code: | | const char AString[][9]={"12","1234","123","1","12345678"}; //Here I put the longest array in it's 8+1. Now the compiler calculate the rest. This waste a lot of space. |
| Code: | | const char *AString[5]={"12","1234","123","1","12345678"};//This is pointer to 5 string, wont work in CCS? |
How to define with minimum over heat.
Hints? |

Read the manual.
Look at the section "Using Program Memory for Data".
Look at what the '*' specifier is used for. |

Thanks for hints:-)
The solution is on page 34 in the CCS PDF:
| Code: | The compiler allows a non-standard C feature to implement a constant array of variable length
strings.
The syntax is:
const char id[n] [*] = { "string", "string" ...};
Where n is optional and id is the table identifier.
For example:
const char colors[] [*] = {"Red", "Green", "Blue"}; |
