Find your way

Easily navigate through performs, gotos and calls, within one or between several files.

Everything at a glance

Just double-click to see what a procedure references and what is it referenced by, as well as all variables it uses.

Structure uncovered

See your procedures sorted alphabetically, by sections or as a perform-hierarchy.

Incredibly fast and beautiful

Based on the FastColoredTextBox-project and combined with Adobe's Source Code Pro font, analysing COBOL was never more delightful. And all that in less then 4MB.

Where is that defined?

Just double-click on any variable to see its definition, double-click again to jump to the source.

Made for humans, not compilers.

Let CANAL find copy-books and insert them into the source code for you.
