Command |
Description |
---|---|
c |
"Continue". Switch from stepping to tracing, thus tracing the remainder of the execution of the word being debugged. |
d |
"Down a level". Mark for debugging the word whose name was just displayed, then execute it. |
u |
"Up a level". Un-mark the word being debugged, mark its caller for debugging, and finish executing the word that was previously being debugged. |
f |
Start a subordinate Forth interpreter. When that interpreter exits (with resume), control returns to the debugger at the place where the f command was executed. |
g |
"Go." Turn off the debugger and continue execution. |
q |
"Quit". Abort the execution of the word being debugged and all its callers and return to the command interpreter. |
s |
"see". Decompile the word being debugged. |
$ |
Display the address,len on top of the stack as a text string. |
h |
"Help". Display symbolic debugger documentation. |
? |
"Short Help". Display brief symbolic debugger documentation. |
debug name |
Mark the specified Forth word for debugging. Enter the Forth Source-level Debugger on all subsequent attempts to execute name. After executing debug, the execution speed of the system may decrease until debugging is turned off with debug-off. (Do not debug basic Forth words such as "dup".) |
(debug |
Like debug except that (debug takes an execution token from the stack instead of a name from the input stream. |
debug-off |
Turn off the Forth Source-level Debugger so that no word is being debugged. |
resume |
Exit from a subordinate interpreter, and go back to the stepper (See the f command in this table.) |
stepping |
Set step mode for the Forth Source-level Debugger, allowing the interactive, step-by-step execution of the word being debugged. Step mode is the default. |
tracing |
Set trace mode for the Forth Source-level Debugger. Tracing enables the execution of the word being debugged, while showing the name and stack contents for each word called by that word. |
<space-bar> |
Execute the word just displayed and proceed to the next word. |
