field de_sysnum n(8,0)
field de_histnum n(4,0)

EXACT is on
NEAR is off

Example records:

de_sysnum de_histnum
13609 1
13609 2
13609 4
13609 3
14102 1
1360 1
1360 9

active index is:

transform(de_sysnum,'99999999')+transform(de_histnum,'9999')

want to move to the first record with a de_sysnum of numeric 13609 and then want to scan while...endscan through only those records that have a de_sysnum of 13609 and ANY de_histnum.
