Summary of No value for GDBN

The purpose of a debugger such as No value for GDBN is to allow you to see what is going on “inside” another program while it executes—or what another program was doing at the moment it crashed.

No value for GDBN can do four main kinds of things (plus other things in support of these) to help you catch bugs in the act:

You can use No value for GDBN to debug programs written in C and C++. For more information, see Supported Languages. For more information, see C and C++.

Support for Modula-2 is partial. For information on Modula-2, see Modula-2.

Debugging Pascal programs which use sets, subranges, file variables, or nested functions does not currently work. No value for GDBN does not support entering expressions, printing values, or similar features using Pascal syntax.

No value for GDBN can be used to debug programs written in Fortran, although it may be necessary to refer to some variables with a trailing underscore.

No value for GDBN can be used to debug programs written in Objective-C, using either the Apple/NeXT or the GNU Objective-C runtime.
