HTBasic provides many high level IEEE-488 bus control statements. The actions taken on the IEEE-488 bus by each control statement are determined by three things:
1) whether the device issuing the command is the system controller,
2) whether the device is the active controller, and
3) whether the command was issued with only the interface select code or a primary address was specified.
Each statement is discussed in the following paragraphs. Also, a quick bus actions reference is provided at the end of this section.
