Basic Errors

The basic data and geometry handling procedures and also most of the application procedures have a uniform way of handling errors. Sources for these errors may be category 1 errors or abnormal situations within the procedures themselves. A special stack technique is used so that the program flow can be followed immediately before and after the error situation. In application programs, however, the ideal situation is that the error codes are translated into category 3 errors before being presented to the user.

In certain applications, the error codes may, however, reach the user. This is especially true in Hull.
