The SENDSCAN statement can send multiple scan codes to the PC.

The label is used to specify the start of the scan codes. The first byte specifies the number of bytes that follow.

<span style="font-family: Arial;"> </span>

The following table lists all mouse scan codes.

To emulate a left mouse click, the data line would look like this:

<span style="font-family: Arial;"> </span>

DATA 6 , &H09, &H00, &H00, &H08 , &H00, &H00

      ^ send 6 bytes

              ^ left click

                                      ^ release
