Default Actions

Internal Formats

Some of the default actions taken by Culprit in the two processing modes are based on the internal format that Culprit uses to store numeric fields. Under Culprit Release 5.0, all user-defined numeric input and work fields and extracted-item and total-bucket values for these fields were stored as 8-byte packed values. Under Culprit Release 6.0 and later, these items are stored as 8-byte or 16-byte packed values, regardless of the release option specified, as follows:

The following fields and their associated extracted-item and total-bucket values are stored as 16-byte fields:
- Numeric input fields that specify a DP= keyword expression or that, due to size and data type, contain more than 15 digits
- Numeric work fields that specify a DP= keyword expression, an initial value with a decimal point, or an initial value that contains more than 15 digits
All other numeric input and work fields and their associated extract-item and total-bucket values are stored as 8-byte packed values.

The following table summarizes default actions taken by Culprit under RELEASE=5 and RELEASE=6. These differences are discussed more fully below.

Culprit Facility	Release 5 Default action	Release 6 Default action
Number of decimal positions printed for numeric output fields	2	0
Treatment of arithmetic and MOVE operation results	TRUNCATE	ROUND
Size of intermediate work fields	8-byte packed decimal unless user-defined fields used in the calculation are stored as more than 8-byte packed decimal	16-byte packed decimal
Decimal arithmetic overflows	Overflows truncate the high-order digits; no error message is printed	Overflows invoke the extended error-handling facility
Report headers	Headers print anywhere on a report page if a title parameter is not specified	Headers always print either at the top of a new page, if a title parameter is not specified, or under the title if a title parameter is specified

Default actions taken by Culprit under RELEASE=5 and RELEASE=6 are explained below.

Decimal Positions

The number of decimal positions in output fields are handled in the following manner:

Under RELEASE=5, two decimal positions are printed for all numeric fields unless a DP= keyword expression is specified on a REC, work field, or edit parameter for the field.
Under RELEASE=6, no decimal positions are printed unless a DP= keyword expression is specified on a REC, work field, or edit parameter for the field.

Under both RELEASE=5 and RELEASE=6, a DP= keyword expression is ignored for output fields that specify format codes FP, FZ, FM, FD, FS, FB, FU, and FW.

Truncation/Rounding

Numeric results generated in Culprit procedure logic are truncated or rounded, as follows:

Under RELEASE=5, the results of either a MOVE operation or simple or compound arithmetic operations are truncated, except on COMPUTE statements that specify ROUND.
Under RELEASE=6, the results of either a MOVE operation or simple or compound arithmetic operations are rounded, except on COMPUTE statements that specify TRUNCATE.

Work Field Storage

Internal work fields for compound arithmetic operations (that is, arithmetic operations that specify COMPUTE) are handled as follows:

Under RELEASE=5, intermediate work fields are stored as 8-byte packed fields, provided that all user-defined fields in the COMPUTE statements are stored as 8-byte fields. If any are stored as 16-byte fields, all intermediate work fields are stored as 16-byte packed fields, regardless of the processing mode in effect.
Under RELEASE=6, intermediate work fields are stored as 16-byte packed fields.

Note: A COMPUTE instruction that includes multiplication by a power of 10 to shift high-order digits from an intermediate work field will produce different results depending on the processing mode in effect.

Decimal Overflow

Decimal arithmetic overflows in computed results are handled as follows:

Under RELEASE=5, decimal arithmetic overflows that occur in a multiplication operation do not produce an error message; the overflow causes high-order digits to be truncated without warning.
Under RELEASE=6, a decimal arithmetic overflow results when an attempt is made to store a computed result that contains more than 15 significant digits in an 8-byte packed work field. The overflow invokes the extended error-handling facility.
Note: For more information on the extended error-handling facility, see the CA Culprit for CA IDMS Messages and Codes Guide.

Report Headers

Report headers are handled as follows:

Under RELEASE=5, report headers print anywhere on a page unless a title is specified and a space code of 1 (that is, a space code that designates a new page) is indicated for the first header line.
Under RELEASE=6, report headers print at the top of a new page unless a title is specified. If a title is specified, the title prints at the top of the page and headers follow the title, as determined by user-coded space codes.
