Public array variable "lost"

I have an array defined as a public variable

public gaPos

I can happily populate the array but when I reference it in a form's
method the I get a compilation error - Unable to find Unknown gaPos

The code is as follows:

li = ALEN(gaPos, 1)
i = 0

lcValue = gaPos(1)

the variable li contains the correct number of elements in the array but
the lcValue = gaPos(1) line generates the above compile error.

other none array Public variables seem fine in the method.

What have I missed?


thanks

Try using the square bracket syntax:

lcValue = gaPos[1]

The compiler doesn't know that gaPos is an array - it looks like a
function call, and is not found.

(At least, that's my guess).

Do you get the error during compiling your form or when you build the project?

In the latter case, just add a line
EXTERNAL ARRAY gaPos
to every method or program file, where you use this array.

Hi Peter,
Define your public array like

Public Array gaPos[1]

It is incorrect. Try
? sqrt[2]
It will print the square root of 2. It is not an array reference. For
real fun, try
? sqrt[2)
VFP will throw the error "Function name is missing )."!

this seems to have fixed the problem.

What I don't understand is why this is the only array affected ...


thanks all for your help.
