Option Variable Clauses
Clauses

@OVERFLOW
When a value does not fit within its formatted width, ENFORM replaces the value
with overflow characters. When this clause is set to a single ASCII character,
ENFORM prints that character when overflow occurs. The default overflow
character is an asterisk (*).
If you set @OVERFLOW to ASCII blank, ENFORM truncates the value in a field
whenever an overflow occurs instead of replacing the value with blanks.
@PAGES
specifies a maximum number of pages to print per report. The default value is
32,767 pages.
@PRIMARY-EXTENT-SIZE
specifies the primary extent size of the output file. If necessary, the file will be
created with an extent size larger than the one you specified.
When this clause is not set, ENFORM calculates an estimate of the primary and
secondary extent sizes needed for each output file. The estimate could be too
large, 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 must create a new output file, with a larger
extent size, and copy the data from the full file into the new file. This results in
very inefficient processing.
@READS
specifies the maximum number of records to be returned from the data base per
ENFORM program. This is a useful tool when debugging. For an idea of how
many reads are required by a given ENFORM program, see the @STATS Option
Variable clause. 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 uses the primary-extent size.
@SPACE
specifies how many blanks appear between report columns. The default value is
two blanks.
