These commands are available in the Run menu or toolbar, by their shortcut keys, or by right clicking in the Edit or Run Windows for a context-sensitive menu.
Run (Alt+F3) starts a stopped, paused, or unstarted program.
Pause (Alt+F4) pauses a running program.
Continue (Alt+F2) continues a paused program.
Stop (Alt+F10) stops a running program.
Reset HTBasic
(Ctrl+Break) stops a running program and resets HTBasic. The program is retained in memory.
Clear I/O
(Alt+F5) aborts an I/O operation that is in progress and pauses the program. Unless timeouts have been enabled, the system will wait indefinitely for an I/O operation to complete. Clear I/O from the Run menu forces the program to return to a paused condition. Executing a CONTINUE function (Alt+F2) causes the I/O statement to be re-executed.
