13!:x New Debug Facilities | initial writing: 2001-11-08 last updated: 2002-09-10

A debug suspension is an immediate execution state with a non-empty execution stack. Another debug suspension is created when a named object (verb, adverb, or conjunction) is invoked in a debug suspension and it too suspends.

Four new verbs are provided. See the dictionary.

The result of`13!:13` is extended to have a column 8, which contains a`*` if the stack level begins a suspension, and a blank otherwise. In the display produced by`13!:1` and in the result produced by`13!:18` ,`` a line begins with a`*` if the stack level begins a suspension (other lines begin with a`|` ).
