dear sir..

i plan to use 2d array to store the file name and then display it to the LCD..

but cant make it success ... is that any suggestion to make it the array work?

[mackrackit]

The best I can do is tell you to start a new thread about the 2D array problem. I have not tried them myself.

Be sure to post your code when you start the new thread...

i already tired to try the 2d array but it still cannot work....

is that any way to store the file name except using the 2d array?

[mackrackit]

If you do not want to post your code and ask about why it does not work I guess there is not much anyone can do to help. You have not even explained exactly what you are trying to do.

It seems like you now have the VDIP running. So if you want help with arrays or something else start a new thread as suggested.

so sorry,
i got post my coding..but dunno y cant display...

now the coding not at me..later i will post again for the coding...thank for your inform

dear sir,

y when i put the line @Put2D(X,Y) then cannot compile got error

Error[108] C:\USERS\PIC16F873A\ARRAY TEST 2\ARRAY2.ASM 311 : Illegal character (()
