Option Variable Clauses
This condition does not mean an Enform Plus session that meets criteria for level 2
will always take less time to run than another Enform Plus session that requires
level 7. The execution time also depends on the amount of data that must be
processed.
When not set or set to 0 (zero), Enform Plus proceeds with whatever strategy it
chooses.
If the specified strategy is exceeded, an error message is received and the Enform
Plus program stops.
The desired cost tolerance level can be defined as follows:
@DATE-FORMAT
specifies a default format for printing dates when AS DATE * is used. For date
format specifications, see the AS DATE Clause on page 5-22. The default is
"M2/D2/Y4".
@DECIMAL
When set to a single ASCII character, Enform Plus prints that character for a
decimal point. Enform Plus also accepts the specified character in place of a decimal
point in a numeric literal. The default value is the period character (.).
@DISPLAY-COUNT
determines how many lines to display on output device at one time. When number
lines have been displayed, Enform Plus pauses. To continue the display, press the
Return key. Execution of the Enform Plus program, while at the pause, can be
aborted by any of the following:
•
Entering two slashes (//)
•
Pressing the Ctrl and Y keys simultaneously
•
Pressing the Break key
0
Allows the Enform Plus session to proceed with no cost limit.
