The TEPAM Introduction page at contains a couple of errors:

1. The PROCEDURE DECLARATION section, 2nd paragraph after the example code, says "The procedure body on the other hand is identical between a command declared with proc and a command declared with procedure", but the example code contains asterisks in the body which aren't part of a normal "proc" declaration. If they're not formatting errors, the text doesn't explain them.

2. In the FLEXIBLE ARGUMENT DIALOG BOX section, the big example code is missing a trailing square bracket "]".
