It is terminated by a, a with EOI, or an EOI together with the last databyte. QuickBASIC automatically generates an EOI together with the last databyte.Multiple commands in a command line are separated by a semicolon (;). If thenext command belongs to a different command system, the semicolon isfollowed by a colon.Example: This command line contains two commands. The first command belongs to theROUTe system. The second command belongs to the AUDio system and turnson the loudspeaker.If the successive commands belong to the same system and have one or morecommon levels, the command line may be shortened. The second commandfollowing the semicolon then starts at the level that is below the common levels(see also Figure 3–1). The colon after the semicolon must be omitted.Example: This command line is shown in full length and contains two commandsseparated by a colon. Both commands belong to AUDio command system (thatis, they have two common levels).In the shortened command line, the second command starts at the level belowAUDio. The colon after the semicolon must be omitted.The shortened form of the command line is: However, a new command line always starts with the full path.3–8 DDS200 Digital Demodulation System User Manual
