Option Variable Clauses
creating a file system error 43 unable to obtain disc space for file extent; or the
estimate could be too small, producing more data than the file can hold. Each time
an output file is full, Enform Plus must create a new output file, with a larger extent
size, and copy the data from the full file into the new file. This strategy results in
very inefficient processing.
@READS
specifies the maximum number of records to be returned from the database per
Enform Plus program. This option is a useful tool when debugging. For an idea of
how many reads are required by a given Enform Plus program, see the @STATS
Option Variable clause under Option Variable Clauses on page 5-48. To remove a
limit, set the @READS Option Variable to 0 (zero). The default value is 0, meaning
an unlimited number of records can be returned.
@SECONDARY-EXTENT-SIZE
specifies the extent size of the output files. If necessary, the file will be created with
an extent size larger than the one you specified.
When this clause is not set, Enform Plus uses the primary extent size.
@SPACE
specifies how many blanks appear between report columns. The default value is two
blanks.
@STATS
When set ON, Enform Plus prints the statistics regarding the records after the
Enform Plus program is completed. Enform Plus prints the following statistics:
The default value is OFF.
@SUBTOTAL-LABEL
specifies a character string that is to appear on the same line as and to the left of the
subtotal. Enform Plus prints the character string in the column of the group item
over which the subtotal is computed. If the item is defined with the NOPRINT
clause, Enform Plus does not print the character string. If the character string does
FILENAME Physical file name of a set of records.
LEVEL READ Order in which this file was read in relation to all physical files
read. The first file read is indicated by the number 1.
RECORDS READ Total number of logical records read from this physical file.
POSITIONS Total number of positioning operations performed to read this
physical file.
STRATEGY COST Number, 1 through 8, used to represent the cost of the strategy
Enform Plus developed to handle the Enform Plus program. For a
definition of the cost numbers, see the @COST-TOLERANCE
option variable under Option Variable Clauses on page 5-48.
