Hi,

I spotted a couple of things recently in V1.42.  Appologies if these have already been discussed:-

With the following code snippit and the CARRYX directive set, this loop does not loop, but exits immediately.

TestVar = 1

	do
	loop until TestVar = 0

-----------------------------------------------------------------------

The following Macro declare and then using it, actually works:-

\IO_Port	EQU 	ra


\MacroTest	MACRO 
\	setb	IO_Port.\1
\ENDM



\MacroTest 1


But when enclosed within ASM ENDASM like the following it does not:-

\IO_Port	EQU 	ra


ASM

MacroTest	MACRO 
	setb	IO_Port.\1
ENDM

ENDASM


\MacroTest 1

-----------------------------------------------------------------------

The following produces an error about too many parameters:-

TestVar = 1+8+1               ' Data bits for Serial Comms (1 start, 8 data, 1 stop)

-----------------------------------------------------------------------

I noticed that the following produces the error "CONSTANT EXPECTED"

TestCon2		CON	TestCon1
TestCon1		CON     123

Since the order that they are defined is out of sequence, so to speak.  Is this a fundamental feature of compiler / SASM ?
Also, any DATA statements that are used must be before the line of code that references them.  Will this change or is likely to be the norm.

Many Thanks,
Tony
