If the condition of the IF is true, then the rest of the multi-command line is executed, if the condition of the IF is false, the rest of the multi-command line is ignored. This is apparently not legal in HP-71B BASIC...

Unless I'm misunderstanding you, it is legal in HP-71 BASIC. For example:

IF 1=1 THEN DISP "TRUE" @ BEEP @ BEEP ELSE DISP "FALSE" @ BEEP

This displays TRUE and beeps twice. Change the 1=1 to 1=2 and it'll display FALSE and beep once.
