A big D on my hat - ardentcrest - 2014-02-18

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).

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

Re: A big D on my hat - ardentcrest - 2014-02-18

mine 1.4.0-s1860

remember I'm using borIDE

Damn it!
I forgot to upload the fix! Confusedhock: And the packing script is in a machine 2500km away from me :oops: :lol:
Will try to upload the new version tonight.

Re: A big D on my hat - ardentcrest - 2014-02-19

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$

Re: A big D on my hat - ardentcrest - 2014-02-19

got it Smile

I have to learn basic all over again, not just for the spectrum but for the compiler :evil:

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

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,"
