RESUME Abbr. resU
RESUME line number
RESUME NEXT
Works with the TRAP command, which catches program errors. Use
RESUME to return to the current program after an error is found by a TRAP
command. RESUME works only in conjunction with TRAP; RESUME cannot
continue program execution unless the program is suspended by a TRAP
command.
Parameters: line number or NEXT
1. If you issue a RESUME command with no parameter, execution resumes at
the line where the error occurred. The computer will then try to execute this line
again.
2. If you include a line number after the RESUME command, the program
goes to that line and resumes execution there. Any line number that appears in the
program can be used. If you use a line number, do not also type NEXT.
3. If you type NEXT, the program resumes execution at the line after the one
that contained the error. The erroneous line is not reexecuted. If you use the
NEXT parameter, do not also use a line number parameter.
Examples: RESUME S50 Restarts the program at line 250.
RESUME NEXT Resumes execution at the line following the one that
contains the TRAPped error.
RETURN Abbr. reT
Ends a subroutine and returns program execution to the line after the last
GOSUB command. RETURN is always paired with a GOSUB command. See
GOSUB.
RGR Abbr. rG
RGR (number)
