The ta statement toggles or resets the type-ahead buffer.
ta [on|off|clear|exp]
| on | Turns on the type-ahead buffer. |
| off | Turns off the type-ahead buffer. |
| clear | Clears the type-ahead buffer. |
| exp | The type-ahead input buffer is turned on if the expression evaluates to nonzero (true) and turned off if it evaluates to 0 (false). |
The BASIC ta statement is equivalent to the TCL type-ahead command and the BASIC inputclear statement.
