Hi all,
I'm using this code to load an array with a certain text string
I have many different string in variuos parts of the program and this code consumes a lot of space, so I would like to optimize it using macros .
It's easy to store the string in code space and then with a macro retrieve the address and read it:
Now I have some difficulties to continue: instead of print the string, I need to store it in RAM, the same things that does ArrayWrite.
So the macro should be modified to accept as parameters, the source ROM string and the destination address in RAM
Something like
So calling the macro I can specify any string stored in ROM and any RAM destination where to put it.
Could anybody help me to complete the macro ?
Thanks
Marco

peekcode w0, x
if x then
debug x
w0=w0+2
endif
until x=0 ' print till end of string '0'
