After some more tests, it works perfectly for all memory overflow tests :
The secret is to label the beginning of each memory bank (X,Y and P)
For example:
ORG x:0
xmem_start:
first_x_variable dc 0
...
; Test the overflow of the internal X memory bank
IF (*-xmem_start)>$200
FAIL "Internal X memory overflow:",(*-xmem_start)
ENDIF
ORG x:$2000
nth_x_variable: dc 0
; Test the overflow of the external X memory bank
IF (*-xmem_start)>$4000
FAIL "External X memory overflow:",(*-xmem_start)
ENDIF
Then, you do the same for Y memory :
ORG y:0
ymem_start:
first_y_variable: dc 2000
IF (*-ymem_start)>$200
FAIL "Internal Y memory overflow:",(*-ymem_start)
ENDIF
and so on for every bank of memory you have to test.
And of course, the same for the P memory.
; Interrupt vector 0, start address of the DSP program
ORG P:0
startcode: jmp <$40
; Begining of the code
ORG P:$40
...
In fact, you just have to set the 3 variables
xmem_start
ymem_start
pmem_start
and all the compiler memory tests can be done with the * character.
Thanks again ggn.

Thadoss.

What's the anti-troll code?
