| RANDOMIZE USR issue |
|

I'm trying to compile a short menu program including a RANDOMIZE USR command which calls an external assembly routine (tested).
Using both the latest ZXB v.1.7.2 and the previous v.1.6.12, the compiled program freezes. Recompiling it without the RANDOMIZE USR command, all goes ok!
Even trying to change the memory addresses, it seems the problem persists between the RANDOMIZE USR instruction and something inside the code...
Code: DIM y,a,i AS UBYTE
y=10: a=0: i=1
10 BORDER 0: PAPER 0: INK 0: CLS: POKE 32005,0
RANDOMIZE USR (address of the external tested routine)
20 PRINT AT y,11; BRIGHT 1; OVER 1; INK i;" "
IF a < 10 THEN a=a+1
ELSE a=0
END IF
IF a=10 THEN
IF i < 7 THEN i=i+1
ELSE i=1
END IF: END IF
IF (INKEY="1" AND y <> 10) THEN GOSUB 70: y=10: POKE 32005,0: END IF
IF (INKEY="2" AND y <> 11) THEN GOSUB 70: y=11: POKE 32005,1: END IF
IF INKEY="3" THEN BEEP .04,50: RANDOMIZE USR (game start address): GO TO 10: END IF
GO TO 20
70 PRINT AT y,11; BRIGHT 0; OVER 1; INK 7;" ": BEEP .04,50: RETURN
Thoughts?

Maybe the question could result dumb to Assembly experts; however, is there a way to make an ORiGin memory address flexible? Saying it more clearly, even setting an ORG value in the ZXB commandline, is there a way to import the code into a new memory address?

Well, long time I don't announce new releases here (usually goes to Facebook or twitter).
This one is version 1.7.0 which includes:
- Some fixes and better stability
- Added (finally! 8) ) READ, DATA and RESTORE which, essentially work very much like the ones in Sinclair BASIC (i.e. DATA with complex expressions supported)
- Can now call SUBs with no parenthesis: mysub 1, 5, a, 3*c (expanded syntax)
- Can now call FUNctions with 1 or no parameters with no parenthesis.
