This may be a DIM question but...

[John Strasser]

Thanks Folks

Never realized that you could declare variables straight off with local/global/static.

Fwiw, I've just tested it in the console compiler 4.04.0042 and it works just fine.

Here's the program code

    STATIC x,y,z AS LONG
    x=1
    y=2
    z=3
    PRINT x,y,z

Thanks again.

>Break the habit of Dimensioning ("Dim") a variable and use "Local" instead

I will second that nomination.

I never use DIM at all.

All variables - scalars and arrays, are defined with..

   LOCAL |STATIC |GLOBAL  varname      AS [i]vartype[/i]   ' scalars
   LOCAL |STATIC |GLOBAL  arrayname() AS [i]vartype[/i]   ' arrays

Arrays are REDIM'd when they need elements defined.

I also like that this way allows all array variables to be defined in the same physical area of the source code where the scalar variables used in a prodedure are defined.. i.e., everything is one place.

Works for me.

Without getting into the whole Help File definitions, I did a quick test and got the following:

#COMPILE EXE
#DIM ALL

FUNCTION PBMAIN () AS LONG
'*** Cliff's Original
''    dim x, y, z AS LONG       '<--- Does not work
'    LOCAL x, y, z AS LONG     '<--- Works
'    x=1
'    y=2
'    z=4
'    MSGBOX "x+y+z=" + STR$(x+y+z)
'
'
''*** Mel Bishop version 7                   <--- Works in 8.03.0040
'    DIM x AS LOCAL LONG      '
'    DIM y AS LOCAL LONG      '
'    DIM z AS LOCAL LONG      '
'
''    LOCAL x as long
''    local y as long
''    local z AS LONG     '<--- Works
'    x=1
'    y=2
'    z=4
'    MSGBOX "x+y+z=" + STR$(x+y+z)
'
'
'*** Cliff Modified from multi-Line to single line
    DIM x, y, z AS LOCAL LONG      '<--- Not work
    x=1
    y=2
    z=4
    MSGBOX "x+y+z=" + STR$(x+y+z)
'******************************************************************************
'*** So I would say the long and short of it, if declaring a variable
'*** Break the habit of Dimensioning ("Dim") a variable and use "Local" instead
'*** if you want to have multiple variables declared on the same line
'*** (Someone else may have a better explanation though)
'******************************************************************************
END FUNCTION

I had to convert it to PB/win 7.04 but the following does work.

#COMPILE EXE
#DIM ALL

FUNCTION PBMAIN () AS LONG
    DIM x AS LOCAL LONG      '
    DIM y AS LOCAL LONG      '
    DIM z AS LOCAL LONG      '

'    LOCAL x as long
'    local y as long
'    local z AS LONG     '<--- Works
    x=1
    y=2
    z=4
    MSGBOX "x+y+z=" + STR$(x+y+z)
END FUNCTION

So, changing your example from "DIM x,y,z AS LONG" to "DIM x,y,z AS LOCAL LONG" should work but I don't have version 8.x to test it.

John,
Almost immediately I was going to post the answer is "YES", but then a moment hit me and remembered that although you can Dim a variable, (and I am in the habit of it myself, bad habit mind you), that I am trying to relearn to use Local rather than Dim because if you stop and think about it...."Dim" would technically be "Dimension" (meaning Arrays and such). or from the help files

DIM statement
Purpose: Declare and dimension arrays, scalar variables, and pointers.

That said a simple example will show you that Dim will not work the way you want, but Local will

#COMPILE EXE
#DIM ALL

FUNCTION PBMAIN () AS LONG
'    dim x, y, z AS LONG       '<--- Does not work
    LOCAL x, y, z AS LONG     '<--- Works
    x=1
    y=2
    z=4
    MSGBOX "x+y+z=" + STR$(x+y+z)
END FUNCTION

Hi Folks,

While learning DDT (I haven't used PB since 3.5 was a NEW release ) and so I'm finding that I fall back on the console compiler a lot (whatever works) I started wondering...

Is it possible to DIM more than one variable on a line?

The code would be: DIM x,y,z As LONG

Obviously you're not going to do this for major variable, but for little test programs and loop counters I've always found it useful.
