nStatusCode is the status code that was
set.CApphot:GetStatusCode
Returns the status code generated by the GetImageParams and Measure methods. If either of these methods encounters an error it sets the value of the nStatusCode class member which is accessed using this method. The codes are described in the documentation for each of these methods.

nStatusCode = CApphot:GetStatusCode() where |
nStatusCode is the status code that was
set.
The status code works differently for different methods:
For the
Measure method,
the status code is 0 or a negative number corresponding to
the error that occured.
For GetImageParams,
the status code is 0 or a positive number made from a
bit-wise OR of error flags. The particular errors that occured can
be decoded using the BitTest function. The error flags are listed under
the GetImageParams topic.
