Hi Jose, can you take a look at this. To run it you need the spectranet running in fuse. but I'm getting a crash when running it. I think it has something to do with the way i'm using the DIM thekeys$

I hope you can help, as I feel if it cant be fixed I'm going to have to rework the inkey routine all over again, this time poking it right to memory, and I've no idea how to do that.

Try running this program:
Code: GO TO 10
sample:
asm
defb "A(B)CD"
end asm
10 DIM a,i AS UBYTE
FOR i = 0 TO 5
LET a=PEEK(@sample+i)
PRINT a;" '";CHR$(a);"'"
NEXT i
It was supposed to produce this output:
Code: 65 'A'
40 '('
66 'B'
41 ')'
67 'C'
68 'D'
However it will produce this output instead:
Code: 65 'A'
32 ' '
40 '('
66 'B'
41 ')'
67 'C'
Apparently this extra space (code 32) mysteriously appears whenever there's parenthesis inside a defb string.
Tested using latest version 1.4.0s1902. This problem always happens regardless of optimization level for compilation.

| SAVE inside SUB freezes the program (*solved*) |

I'm making a program to print customized labels with the ZX Printer. I was going to make load/save of label data.
The problem is when using SAVE in any of its variants inside a SUB. It freezes after saving is done, and the saved data is different from when the SAVE is done in the 'main block'.
The LOAD command does work inside a SUB.
I don't know if it has some relation to the previous bug report about SAVE:
<!-- l --><a class="postlink-local" href="https://forum.boriel.com/bug-reports/save-bug-solved-t858.html">bug-reports/save-bug-solved-t858.html</a><!-- l -->
Here is a little program that reproduces the error:
Code: dim variableToSave as uinteger
variableToSave = 1234
sub saveSomething()
' This freezes the program AFTER saving is done
save "test1" DATA variableToSave
' This freezes the program AFTER saving is done and shows a funny "demo"
'save "test1" screen$
end sub
sub waitForAKey()
while inkey$=""
end while
while inkey$<>""
end while
end sub
print "Press any key to start save..."
waitForAKey()
saveSomething()
'This works (in the main block)
'save "test1" DATA variableToSave
print "Save done. Press any key to continue..."
waitForAKey()
' Do some random stuff (the Spectrum freezes before reaching here):
dim i as uinteger
i = 2 + 2
print "i = "; i
print "Press any key to exit..."
waitForAKey()

My next ZX BASIC game requires a lookup table for variable sized data.
The simplest solution would be something like this:
Code: data1:
asm
defb 0,1,2,3,4,5
end asm
data2:
asm
defb 6,7,8
end asm
data3:
asm
defb 9,10,11,12
end asm
DIM array(1 TO 3) AS UINTEGER = { @data1, @data2, @data3 }
But compiling this program using latest version of ZX BASIC (incorrectly) produces the following error messages:
Code: prog.bas:14: Initializer expression is not constant.
prog.bas:14: Initializer expression is not constant.
prog.bas:14: Initializer expression is not constant.
Another alternative would be declaring the lookup table directly in ASM, but ZX BASIC doesn't support mapping arrays to memory addresses either:
Code: DIM array(1 TO 3) AS UINTEGER AT @data
For now, I'm implementing everything "manually" instead of using ZX BASIC arrays. But it would be nice if this problem could be fixed in future releases!
