array won't build

[starmistress]

What are some possible reasons that an array will not get buildt. When the program runs I get an error stating that 'Variable "AIMAGES" Not Found'. The code is as follows:

&& array of images in the directory of the text line
nImages = adir(aImages, cImgDir + '\*.tif')
if nImages < 1
_text = nErrorHandle
\\No images found for <<cImgDir>>
endiff

Straight from the MSDN help file:

&quot;If the array doesn't exist and ADIR( ) returns 0, the array isn't created.&quot;

The best way to avoid the error you're encountering is to either A) Create the array before issuing ADIR() or B) When nImages returns 0, don't try to access your array.

But I know that there is info to be returned. This portion of the program will work on a different machine. Is there an ODBC issue that could stop an array from being built?

Any chance there are embedded spaces in the cImgDir variable? To protect yourself, you might want to go with:

cImgFileMask = '&quot;'+cImgDir + '\*.tif&quot;'
nImages = adir(aImages, cImgFileMask)
if VARTYPE(aImages)<> &quot;U&quot; or nImages < 1
