VB syntax

[MachineMaster]

OK, I'm new at this so I am askin for help. I printed out the Mach Script Language Reference, all 139 pages.
I now have a macro that I have written.

a = GetVar (500)
b = GetVar (501)
c = GetVar (502)
d = GetVar (503)

a= a+1
If a>9 Then b=b+1
If a>9 Then a=0

If b>9 Then c=c+1
If b>9 Then b=0

If c>9 Then d=d+1
If c>9 Then c=0   

Print " " &d &c &b &a
SetVar 500, a
SetVar 501, b
SetVar 502, c
SetVar 503, d
End

I had help writing it. The reason I am writing is this macro does what I need but no where in the 139 pages do I find
GetVar, SetVar or a reference to variables in the 500 - 600 range being persistent.
That leads me to think that the 139 pages that I printed are not what I should be studying.
Where do I find the REAL language reference?

note you have to put a "End If" to follow your If statements. i.e.

if a<(a+1) then
your code here
end if

Scot,
Do you mean an End If after every If statement or an End If after the last If statement in my code?

[poppabear]

after every if

If it's on one line, you shouldn't need an End If. At least you don't in regular VB.

Thanks for all the replies. I am still looking for a good language reference. The Wiki page mentioned does have information not in the Mach Script Language Reference but there still seems to be a lot missing. Most needed for me are actual examples.
I am still not sure if I am supposed to be looking for VB Scripting or VB Programming or is there a difference?
Is VB something I need to buy or is there a free version?
Programming Macros interests me a lot as I have been using AHHA software's built in macro language for years and this looks to have even more possibilities.

Darrel there is NOT alot published on the EXTRAS that were added in .  THere is a little in the Customising Mach manual that gives the very basics.

You just have to ask if you need to know something and HOPEFULLY someone has already figured out a way.  OR collectively we work on it to come up with a solution or two. (;-)

Hopefully someone creative willl come along and take ALL the post and sort through them and put them in a search engine type arrangement, then we may have a decent library of functions .

Just a thought, (;-) TP

I have been unable to find any where the syntax for using variables in G code in a Macro.
I can declare a variable
V= GetVar (550)
and Print V will print the value that I have stored in 550 but if I use

V= GetVar (550)
Code "G90 G00 XV YV" or
Code "G90 G00 X&V Y&V"

it runs ok in the script window but Mach gives the error

No digits found where real number should be

What am I doing wrong?

Try this:

Code "G90 G00 X " &V & " Y " &V
