[PIC] IRP bit must be set manually for indirect access

[Mzz Amin]

I'm facing this problem while compiling my code using mikroc for PIC16F877.
that's my code:

And igot this message

IRP bit must be set manually for indirect access to 'nb' variable calcul.c

 

[FvM]

This lines makes no sense

*nbr=&nbre[j] ;

do you mean

nbr=&nbre[j] ;

P.S.: Here you are assigning incompatible types, too
nbre[j]=nbr;

That happens with mikroC Compiler when you use PIC16F. In your code there are a lot of strings which are in RAM. As mikroC doesn't generate auto bank switching code this problem arises. The solution for this is to declare all your strings used for UART_Write_Tect() function as const char so that RAM is freed. Then you have to use CopyConst2Ram() function. Try searching CopyConst2Ram in Google or mikroe forum.
