A big D on my hat
#1
How do I do,

Code:
dim a$(3)
for f=1to 3
read a$(f)
data "text1","text2","text3"

At the moment, ZX BASIC does not support read, data.
You have to do:
Code:
a$(1) = "text1"
a$(2) = "text2"
...
If you need to reset a$ from time to time, put it in a subroutine.
Note: Support for READ, DATA and RESTORE is planned (for backward compatibility).

Code:
dim v$(10)

v$(1)="n"
v$(2)="s"

This seems a bug I've recently fixed. Can you check you have the latest version? (1.4.0s1860)

Code:
for i=1 to len(q$)-1
if q$(1 to i)=" " and x$="" then let x$=q$( 1 to i-1)
next i

input.bas:38: warning: Empty loop

works if I remove the if line but still give empty loop warning


OK need to add end if but nothing appears in the x$

Try this for an interim solution

Code:
#include "read-data-restore.bas"

SETDATAVALUES( @TESTDATA1 )

WHILE ( NOT DataValuesEndFlag )
    PRINT READDATA() ': PRINT
END WHILE

PAUSE 0

SETDATAVALUES( @TESTDATA2 )

DIM Duration as Float
DIM Pitch as Byte

WHILE ( NOT DataValuesEndFlag )
    Duration = VAL( READDATA() )
    Pitch = VAL( READDATA() )
    BEEP Duration, Pitch
END WHILE

STOP

TESTDATA1:

ASM

DEFM "String1,"
DEFM "string2,"
DEFM "string3,"
DEFM "string4,string5,string6,string7,string8,string9"
DEFB $00          ; Terminating byte

END ASM

TESTDATA2:

ASM

; Frere Gustav
DEFM "1,0,1,2,.5,3,.5,2,1,0,"
DEFM "1,0,1,2,.5,3,.5,2,1,0,"
DEFM "1,3,1,5,2,7,"
DEFM "1,3,1,5,2,7,"
DEFM ".75,7,.25,8,.5,7,.5,5,.5,3,.5,2,1,0,"
DEFM ".75,7,.25,8,.5,7,.5,5,.5,3,.5,2,1,0,"
DEFM "1,0,1,-5,2,0,"
DEFM "1,0,1,-5,2,0"
DEFB $00

END ASM
