* Does a CONTINUE.

The HOP command is a command-only statement. That is, it can only be

issued at the interpreter prompt and cannot be placed in a program.

Syntax

HOP

The HOP command is useful for the following:

* Hopping through a GOSUB or CALL.

* Hopping through a loop (when executed on the last line of the loop).

The breakpoint that the HOP statement sets is reset by the next HOP

statement (only one HOP breakpoint per program).

Example

The following shows an example of the HOP command. The program pauses at

line 110. The HOP command has been issued during that pause.

>LIST

! exam246

100 LET A=3

105 PRINT "HI"

110 PAUSE

120 PRINT A

130 PRINT A+A

140 PRINT A*A

150 PRINT "BYE"

999 END

>RUN

>HOP

130 PRINT A+A

>HOP

140 PRINT A*A

>hop

150 PRINT "BYE"

>HOP

BYE

999 END

STEP Command

The STEP command--or several STEP commands--can single-step through a

suspended program. Specifically, the STEP command does the following:

1. Executes the line that the program is suspended at.

2. Displays the next line to be executed.

3. Suspends the program at the displayed line.
