This section describes areas in which IDL Analyst may provide a greater level of control than IDL itself. Underflow and Overflow In most cases, IDL Analyst routines are written so that computations are not http://www.harrisgeospatial.com/docs/using_idl_Error_Handling.html affected by underflow, provided the system (hardware or software) replaces an underflow with the value zero. Normally, system error messages indicating underflow can be ignored. IDL Analyst routines also are written to avoid overflow. A program that produces system error messages indicating overflow should be examined for programming errors such as incorrect input data, mismatch of parameter types, or improper dimensions. In many cases, the documentation for a function points out common pitfalls that can lead to failure of the algorithm. Missing Values Some IDL Analyst routines allow input data to contain missing values. These routines recognize as a missing value the special floating-point value referred to as “Not a Number” or NaN. The actual value varies on different computers, but it can be obtained by reference to the IMSL_MACHINE function. The manner in which missing values are treated depends on the individual function as described in the documentation for that function. For more information on special floating-point values (including NaN), see “Math Erro

Since the instance of the wrapper object is invoked outside of IDL, the normal debugging capabilities of the IDL Workbench are not available. However, it is possible to obtain this output by setting the IDL_BRIDGE_DEBUG environment variable as described in “IDL_BRIDGE_DEBUG” (Chapter 1, Using IDL). For example, if you set this environment variable to 1, you can see library load errors (on Windows), IDL execution errors, and output from IDL print commands. The appearance of debug information printed to stdout on Windows or UNIX depends upon the value set for the IDL_BRIDGE_DEBUG environment variable: Value Behavior 0 Turn off debug output 1 Turn on debug output, which includes output from library load errors, IDL execution errors, and PRINT statement output To get additional Java-side diagnostics related to finding and loading the native libraries, define the IDL_LOAD_DEBUG parameter on the command line when starting a Java application, as follows: java -DIDL_LOAD_DEBUG
