I don't have my full code here at work, but it basically looks like:

dicomdir = OBJ_NEW('IDLffDICOM', 'D:\dicomdir')
PatientName = dicomdir->GetValue('0010'x, '0010'x)

So PatientName is an array of 'PtrHeapVariables', which I want to
compare with a user entered parameter to determine where to start
reading the images/filenames.

What I tried was various combinations of:
StartOffset = WHERE(*PatientName EQ 'blah');
StartOffset = WHERE((*PatientName) EQ 'blah');
StartOffset = WHERE(*PatientName[*] EQ 'blah'); etc.
however, I only get error messages, so end up having to use a FOR loop
to find the starting location.

Cheers
