Specified number of repetitions:
If no response is received within 3 s of trans-
mission of the command (C$), the command is
resent. If there is no response after 3 repeti-
tions, error processing will commence.
Repetition under set conditions:
A C$ command is executed and the command/
response reception are repeated as long as the
2 characters following the 4th character are 20
or less. 10 WHILE A <= 20
20 PRINT #2, C$
30 B$ = INPUT$(LOC(2), #2)
40 A$ = MID$(B$,4,2)
50 A =VAL(A$)
100 WEND
10 FOR A = 1 TO 3
20 PRINT #2, C$
30 WAIT "3.0", 50
40 A$ = INPUT$(1, #2): GOTO 1000
50 NEXT A
