To continue program execution after a break.
Resumes program execution after CTRL-BREAK, STOP, or END halts a program. Execution continues at the point where the break happened. If the break took place during an INPUT statement, execution continues after reprinting the prompt.
CONT is useful in debugging, in that it lets you set break points with the STOP statement, modify variables using direct statements, continue program execution, or use GOTO to resume execution at a particular line number. If a program line is modified, CONT will be invalid.
