Hi,

I have the following situation:
Num
10
20
30
70
80

I need to set a marker so that automatically the first row is marked as 1, but any row after that, that is 10 more than the previous is marked as 1. But as soon as there is a break in the sequence then all the rest are marked as 0. So in the case above 10, 20 and 30 would be have a marker of 1 as they are all in sequence. But even though 80 is 10 more than 70, both 70 and 80 would have a marker of 0 since there was a gap in the sequence becasue 40, 50 and 60 do not exist.

So far this is where I am:

DEFINE FILE HTEMP
MARKER/I1 = IF (LAST NUM + 10) EQ NUM THEN 1 ELSE 0;
END

TABLE FILE HTEMP
LIST
NUM
MARKER
END


This unfortunately does not work when the start in the sequence is greater than 10, also I'm not sure how to deal with a break in the sequence. Hopefully this makes some sense Razzer

Any ideas?

Thanks!

Jinx.

DEFINE FILE HTEMP
CNTR/I2=CNTR+1;
MARKER/I1=IF CNTR EQ 1 THEN 1 ELSE IF MARKER EQ 0 THEN 0 ELSE
          IF NUM - LAST NUM EQ 10 THEN 1 ELSE 0;
END
TABLE FILE HTEMP
PRINT CNTR NUM MARKER
END

Does this do it for you?

I think it works for this as well.
