Source-Navigator<SUP> TM</SUP>=20
is a powerful code analysis and comprehention tool that provides a =
graphic=20
framework for understanding and reengineering large or complex software=20
projects. Source-Navigator's cross-platform nature also makes it an =
invaluable=20
code porting tool.</P>
<P class=3DBody><A name=3DpgfId-1065902></A>Source-Navigator parsers =
scan through=20
source code, extracting information from existing C, C++, Java, Tcl, =
<KBD=20
class=3DCode>[incr tcl]</KBD>, FORTRAN, COBOL, and assembly programs and =
then use=20
this information to build a <EM class=3DEmphasis>project database</EM>. =
The=20
database represents internal program structures, locations of function=20
declarations, contents of class declarations, and relationships between =
program=20
components. Source-Navigator graphical browsing tools use this database =
to query=20
symbols (such as functions and global variables) and the relationships =
between=20
them. </P>
<P class=3DBody><A name=3DpgfId-1065906></A>In addition to the languages =
supported=20
in the standard distribution, you can use the Source-Navigator Software=20
Development Kit (SDK) to add new parsers and extend Source-Navigator=20
functionality to other languages. For more information, refer to <A=20
