Hi Frank,
You sure push the Run Command to the limit... ;-)
I guess the problem here is a matter of scope. When you run the command
string it is actually
executed in the scope of MapInfo, and not in the scope of your MapBasic
application.
And this also leads to the error message you are recieving: MapInfo doesn't
know of any variable
called "myVar2".
Why don't do this using a procedure insted ?
*************************************************************
Declare Sub Main
Declare Sub NoteArrayValue(arrValues() As String, ByVal nItem As Integer)
Sub Main
Dim arrVal1(5), arrVal2(5) As String
arrVal1(1) = "Value 1 in array 1"
arrVal1(2) = "Value 2 in array 1"
arrVal1(3) = "Value 3 in array 1"
arrVal1(4) = "Value 4 in array 1"
arrVal1(5) = "Value 5 in array 1"
arrVal2(1) = "Value 1 in array 2"
arrVal2(2) = "Value 2 in array 2"
arrVal2(3) = "Value 3 in array 2"
arrVal2(4) = "Value 4 in array 2"
arrVal2(5) = "Value 5 in array 2"
Call NoteArrayValue(arrVal2, 5)
Call NoteArrayValue(arrVal1, 1)
'etc...
End Sub
Sub NoteArrayValue(arrValues() As String, ByVal nItem As Integer)
Note arrValues(nItem)
End Sub
*************************************************************
And even this is more or less overkill:
Note ArrVal2(5)
will also do the job, but of course it all comes down to what exactly you
are trying to
achive ?
HTH,
Peter

Vedr.: MI-L passing variable names
05-09-2002

I have a set of array variables, let's call them myVar1, myVar2 etc.
I want to extract a value from one of my arrays, based on an integer that
gets passed, along with the name of the array to get it from.
ie:
I want to get myVar2(10) and note it.
so...
passedInteger = 10
varName = myVar2
myCommand = "note " + varname + "(" + passedInteger + ")"
run command myCommand
which should resolve to myVar2(10) which in turn resolves to give the value
contained in the array. However, I get an error telling my that the
variable isn't defined - it is.
Any comments? Hope I've made myself clear...
Thanks a lot, as always
Frank
