i tried to make a space but it's still said "missing ';' before '_at_'" i wrote : char idata nim[14] _at_ 0x00; and is idata starting address at 0x80? and data starting address at 0x00? so, if i want to set an array starting at the first address of idata, is it right if i define the array as idata and starting address at 0x00? or i should starting at 0x80? thanks very much sincerly, hardian
You should only use absolute addressing when you need to access external memory In general, you wouldn't need it for external memory (XDATA). Only use it if there's a specific reason why something has to be at a specific, fixed address location. otherwise, let the compiler sort out the allocation of variables in the available memory space.
