Range comparsion using BC3.0

[Zoë]

You can't. BC doesn't have any support for numeric tolerances.

[cgtan 2020]

I have a text file which include some parameter that need to be in range
example below, the AT (71654.423000, 71388.499000) need to be in the range of +/- 500.00 of a example reference value 72000, how can I achieve this kind of compare using BC3.0?

DO: Workpiece AT (71654.423000, 71388.499000)

.patt: Workpiece
.ref frame: 71654.423000, 71388.499000, 0.000000
