Wrong amount of memory space reserved?!

Mario Lorber

Hi all!

I have a problem with the definition of memory space in the e.g. XT memory.
I defined a segment, like above, with 1 byte length.

?XT?MEMORY_SIZE?mifare_main SEGMENT XDATA

RSEG    ?XT?MEMORY_SIZE?xxxxxx_main
MEMORY_SIZE:  		DS      1
		memory_blocks  	XDATA    $ - MEMORY_SIZE

In the *.M51 file where you can find all memory locations it says that there are 12H bytes reserved, and I don't know why!

            XDATA   0036H     0012H     UNIT         ?XT?MEMORY_SIZE?xxxxxx_MAIN

For analysis purposes I defined the same segment in the STARTUP file and was watching again at the *.M51 file. There the compiler reserved just 1 byte, like he should do!

Can someone help me with that?
Thanks in foreward!
