Option Variable Clauses
display-format
specifies the default format for printing dates or times when AS DATE * and AS
TIME * clauses are used; it must be enclosed in quotation marks.
@BLANK-WHEN-ZERO
When set ON, Enform Plus suppresses the printing of target-item or by-item
values of zero in reports. When set OFF, zeros are printed. The default is OFF.
@BREAK-KEY
When set ON, pressing the Break key while a query is running either terminates
output (if output is being produced) or terminates the current query and returns you
to the Enform Plus prompt. See Section 2, Running Enform Plus for more
information. When set OFF, pressing the Break key temporarily suspends output and
returns you to the Command Interpreter prompt but it does not terminate processing.
Output resumes when you enter the TACL PAUSE command. If the file specified in
the IN option of the ENFORM command is not a terminal, Enform Plus ignores the
Break key regardless of the setting of @BREAK-KEY.
Enform Plus does not store the setting of @BREAK-KEY in a compiled query.
The default is ON.
@CENTER-PAGE
When set ON, Enform Plus centers the report body on the page according to the
smaller of:
•
The listing device's maximum page width
•
The value of the @WIDTH Option Variable
If @MARGIN was specified, that margin value is added to the report body before the
report is centered on the page.
TITLE, SUBTITLE, AT START, AT END, FOOTING, and SUBFOOTING
information is centered on the page only if a CENTER clause was included.
Otherwise, this information appears at the left margin of the report body.
When not set or set OFF, the report is not centered. The default is OFF.
@COPIES
specifies how many copies to print. The default is 1.
@COST-TOLERANCE
can be set to a number from 1 through 8. Setting @COST-TOLERANCE prevents
Enform Plus from executing a strategy that is more expensive than the user wants.
When a larger number is specified, the query processor performs more work than
when a smaller number is specified.
