The following example declares the simple variable A to be a monitor element. When A is used, monitoring information on A is written to file FYLE.

MONITOR FYLE (A)

In the following program, simple variable I, array MON1, subscripted variable MON2[1], and label FINISH are monitored.

100 BEGIN
200
300    FILE TERMOUT(KIND=REMOTE);
400    INTEGER I;
500    LABEL FINISH;
600    ARRAY MON1[0:3],
700         MON2[0:3];
800    MONITOR TERMOUT (I,MON1,MON2[1],FINISH);
900
1000    I := 27;
1100    MON1[0] := I;
1200    MON2[0] := 23;
1300    MON2[1] := MON1[0] * 2;
1400    GO TO FINISH;
1500 FINISH:
1600 END.

When the program is executed, the following output is written to the terminal:

0148 @ 003:000E:4 (00001000)  I =0:=27         (4"00000000001B")
0148 @ 003:0013:4 (00001100)  MON1 [0]=0:=27   (4"00000000001B")
0148 @ 003:0020:4 (00001300)  MON2 [1]=0:=54   (4"000000000036")
0148 @ 003:0024:4 (00001500)  LABEL FINISH
