Hi;

I posted a solution before (30 Sept 2002, 9:24 p.m.) with mistyped values; this is correct.

There is an **X=Y?** function that will do what you want. Look at the samples bellow: (consider FIX 04 as default)

- you already have a number in the X-register; the display looks:

Y: (anything)

X: (your #)

- you place the number you want to compare: (eg: 4) the display looks:

Y: (your #)

X: 4.0000

- now you use the function X=Y?; if your number is 4.0000, the display looks:

Yes

X: 4.0000

- if your number is not 4.0000, the display looks:

No

X: 4.0000

If you are entering a program, you can choose from both:

1) use specific LBL functions (LBL 01, LBL 02, etc.)

If you get in a point where the integer part of the number in the X-register is 1, 2, 3 or 4, you do not need to use X=Y? function; instead, GTO IND ST X will work better. Your program would look like this: (consider step # 20 as a personal choice)

(first program steps)

.

19 PROMPT (you will input your control # here: 1, 2, 3 or 4)

20 GTO IND ST X

21 LBL 01

(steps when X=1)

.

29 RTN

30 LBL 02

(steps when X=2)

.

39 RTN

40 LBL 03

(steps when X=3)

.

.

49 RTN

50 LBL 04

(steps when X=4)

.

.

59 RTN

60 (rest of the program)

2) If your labels have different numbers, your program can be like this:

(first program steps)

.

19 PROMPT (you input your control # here)

20 1

21 X=Y?

22 GTO xx (label with steps when X=1)

23 CLX

24 2

25 X=Y?

26 GTO yy (label with steps when X=2)

27 CLX

28 3

29 X=Y?

30 GTO zz (label with steps when X=3)

31 CLX

32 4

33 X=Y?

34 GTO ww (label with steps when X=4)

35 ...

.

.

nn LBL xx

(steps when X=1)

.

.

.

If you only have options for 1, 2, 3 or 4, you can eliminate steps 31 to 34; like this:

(first program steps)

.

19 PROMPT (you input your control # here)

20 1

21 X=Y?

22 GTO xx (label with steps when X=1)

23 CLX

24 2

25 X=Y?

26 GTO yy (label with steps when X=2)

27 CLX

28 3

29 X=Y?

30 GTO zz (label with steps when X=3)

(steps when X=4)

.

.

RTN

nn LBL xx

(steps when X=1)

.

.

.
