CALC clause

Returns the calculated value for a field.

Synopsis

CALC field

Description

The CALC clause calculates the value for an I-type numeric field. CALC calculates to two decimal places. Leading and trailing zeros are suppressed.

Multiple CMQL clauses may be specified in any order. The order of application of CMQL clauses is always the same. The CALC clause is applied after the WITH clause, the SAMPLED clause (if present), and the SAMPLE clause (if present).

Examples

The following MultiValue Basic example creates an I-type field IPCT the value of which is calculated from the values of the fields PRICE and DSCPRICE:

0008 WRITE '197':@AM:'175' ON FP,2 
0009 WRITE '203':@AM:'180' ON FP,1 
0010 
0011 WRITE 'D':@AM:1:@AM:@AM:'PRICE':@AM:'10R' ON DICT.FP,'PRICE' 
0012 WRITE 'D':@AM:2:@AM:@AM:'DSCPRICE':@AM:'10R' ON DICT.FP,'DSCPRICE' 
0013 WRITE 'I':@AM:\(TOTAL(PRICE-DSCPRICE))*100/TOTAL(PRICE)\:@AM:'MR20':@AM:'IPCT':@AM:'10R' ON DICT.FP,'IPCT'
