The treatment of Run to Cursor is very easy: the IDE sets at the relevant line fake break point with the number of repetitions as one. When a break point is reached, it has to be removed from the break point list. There is no need to define special debug command.

6.5.7.2Step Over

The DB##SO command executes the treatment of Step Over. It runs up to the nearest end of line.

Syntax:

DB##SO[N]

where N is a handle of a specified VAC machine.

This command is implemented inside the Harmonica. The algorithm is following: Save the current base pointer

Start the loop

Run to the nearest end of line

Compare the current base pointer with the saved base pointer

If both of them are the same, the step is over - jump to the end the loop, otherwise go to

•the start of the loop.

End of the loop

When the nearest end of line is reached, the VAC machine enters to the halted state. In case of jump or infinite loop or other reason inside line execution, the program may not reach end of line, then it just runs and does not enter halted state.

6.5.7.3Step In

The DB##SI command executes the treatment of Step In. It enters inside function body and runs up to the nearest end of line.

Syntax:

DB##SI[N]

where N is a handle of a specified VAC machine.

This command is implemented inside the Harmonica. The algorithm is following:

Start of the loop

Run to the nearest end of line

•End of the loop

When the nearest end of line is reached, the VAC machine enters to the halted state.

6.5.7.4Step Out

The DB##SU command executes the treatment of Step Out. It returns from function body and runs up to the nearest end of line.

Syntax:

DB##SU[N]

where N is a handle of a specified VAC machine.

This command is implemented inside the Harmonica. The algorithm is following:

Save the current base pointer

Start of the loop

Run to the nearest end of line

•Compare the current base pointer with the saved base pointer
