DATA statements?

[AndyH]

Same here... this error for me, but makes no sense (not changed my code):

Code (glbasic) Select Expand

Reverted back to build 198 and it runs fine (yay for the backups!).

AH!!!! You have to define a LOCAL for the variables you're reading. I'll fix that!

[PeeJay]

Oooh, can this be changed? After all, it is entirely possible you want to read a value into a GLOBAL variable .....

[Kitty Hello]

It's already fixed. Get an update, sleepy head!

[AndyH]

Thanks Gernot

[PeeJay]

Thanks hugely - works a treat now

[AndyH]

Can't thank you for how much easier it is to set up some simple tables of data now. Thanks for this.

Could I possibly ask one more tiny enhancement...


Could you allow an offset to added to the RESTORE label command.  eg:

Code (glbasic) Select Expand

RESTORE scoreValueList  // this points the READ at the start
READ val // returns 1

RESTORE scoreValueList + 5 // this skips ahead 5 DATA values
READ val // returns 6

STARTDATA scoreValueList:
DATA 1,2,3,4,5,6,7,8,9
ENDDATA

[PeeJay]

If we're going for non-standard enhancements, being able to resore to a variable string would be incredibly useful - for example:

Code (glbasic) Select Expand

LOCAL d$="LEVEL"+lev
RESTORE d$

STARTDATA LEVEL1:
DATA 1,2,3
ENDDATA

STARTDATA LEVEL2:
DATA 3,4,5
ENDDATA

STARTDATA LEVEL3:
DATA 6,7,8
ENDDATA

etc

[AndyH]

Good idea Peejay.  It's not actually a totally non-standard way as I used a BASIC in the past where you could do this.  I guess you could do your level trick without the extra labels using the offset,

eg:

GLOBAL offset = (level-1) * sizeOfLevel

RESTORE LEVELS + offset

Hey Gernot, if RESTORE label+offset is too wierd for the language, something like this could work also :   RESTORETO label, offset

[PeeJay]

You could do it with the offset in the example I gave, but only if all the levels held the same amount of data. Since I have a habit of having a continual loop until reaching a termination flag, it wouldn't then work - for example:

Code (glbasic) Select Expand

LOCAL d$="LEVEL"+lev
RESTORE d$

WHILE TRUE
 READ b
 IF b<>-1
  //do something
 ELSE
  BREAK
 ENDIF
WEND

STARTDATA LEVEL1:
DATA 1,2,3,-1
ENDDATA

STARTDATA LEVEL2:
DATA 3,4,5,-1
ENDDATA

STARTDATA LEVEL3:
DATA 6,7,8,9,10,11,12,-1
ENDDATA

etc

[AndyH]

True, and I still think your suggestion is a very good idea.  Just thinking about other ways too.  I guess you could always have another Data block to index your start positions, or an array, but I guess that's just making more GLB runtime code that could perhaps be done simpler if GLB natively supported what you wanted anyway.

[Wild_Duck]

When I tried to use Data statements at the "StartData label:" I get a syntax error. It changes to the command colour after typing it but to white after compiling it.

[Kitty Hello]

How about:

Code (glbasic) Select Expand

STARTDATA common:
 data 1,2,3
ENDDATA
STARTDATA special:
   DATA 1,2,3
ENDDATA

RESTORE common
ReadCommon()
RESTORE special
ReadSpecial()?Or make your own "SkipData: n" function.

[AndyH]

The only problem with making a skip data function would be the need to sequentially read through n number of data statements before you could get to the right point.

I was thinking a RESTORETO command would allow me to treat the DATA as static memory, so I could grab data from any point within (from the offset) quickly without the need to load the DATA into another format (membanks or array) in order to do that.

Help !

I have no idea why, but I`m getting an error when I set up my data statement.

Code (glbasic) Select Expand


STARTDATA dataitems:
DATA 1,"PLAY    ",-1,0,0
DATA 1,"OPTIONS ", 2,0,0
DATA 1,"QUIT    ",-2,0,0
DATA 2,"LEVEL   ", 3,0,0
DATA 2,"VOLUME  ", 4,0,0
DATA 2,"BACKDROP", 5,0,0
DATA 2,"BACK    ", 1,0,0
DATA 3,"EASY    ", 2,1,0
DATA 3,"MEDIUM  ", 2,1,1
DATA 3 "HARD    ", 2,1,2
DATA 4,"100%    ", 2,2,100
DATA 4," 75%    ", 2,2,75
DATA 4," 50%    ", 2,2,50
DATA 4," 25%    ", 2,2,25
DATA 4,"  0%    ", 2,2,0
DATA 5,"ON      ", 2,3,0
DATA 5,"OFF     ", 2,3,1
ENDDATA


Thats the code, but it just throws up a syntax error at the STARTDATA statement, and for the life of me I cant see why ;( Am I missing something trivial ?
