The following is a list of frequently asked questions about processing numeric fields and the impact of the various numeric types. else that would make our package end with an error. The first group of documents may be available from a local system or via an Internet connection, the second group of documents will require an Internet connection. The Source Field is defined as a Binary (or COMP) field with 5 digits and zero decimal positions. Sometimes it is needed to convert packed decimal fields to numeric Or display formats for debugging or analysis purposes. SimoTime Technologies was founded in 1987 and is a privately owned company. able to handle this field as a string. one digit per byte. tip. respectively. The fewer decimal positions of the result field will be rounded because of the ROUNDED keyword on the ADD statement.

For example to store an numeric field of value 987 we would required 3 +1 divided by 2 = 2 Hence an Comp-3 field of length 2 bytes can store a value of +999 to -999 as the limit. It's simply. we need to define a decimal field like DEC-PORTION V9(6) comp-3 and then move the FIELD-NAME-3 to DEC-PORTION to retain the decimal part of the value. For example, I have a 2 character field with value of PR. This document describes how packed decimal values (Computational-3) can be converted to numeric values via File Master using COBOL copybooks. Using DFSORT OUTREC options you can achieve the same. FIELD-NAME-3: 9.
