[PML]demo for Real( STRING, FORMAT ) ?

basically it should look like ( REAL ( CWEI OF CMPR OF SPREF ) * QUAN )

but why am I thinkking that result after this is not something that you really expect? :)

Please give me a demo for Real( STRING, FORMAT ), I want to use in reports

then use sorting

I want to use in reports
CWEI OF CMPR OF SPREF * QUAN
But "CWEI OF CMPR OF SPREF" is string

Thanks.
Yeah,you are right.
I want to count the gross weight of a kind of component.
