XPAND
XPAND expands file limit size of the current work file.
Form
X[PAND] numrecs
Parameter Explanation
numrecs Number of records by which you wish to expand the file
size.
Purpose
The XPAND command increases the file limit size of the current work file
by a specified number of records.
Related Commands
When you use the FILE command to create a new file, RISE asks you for the
maximum number of records the file will contain. If, for example, you
specified 10 lines for the new file, entered 10, and discovered that you
had more lines to add to the file, RISE would return the following
message:
Error 147: No room in edit file; use XPAND.
Using X[PAND] with the number of records you wish to add, you could
enlarge the size of the file as desired. RISE would respond with the
following message, when the expansion is accomplished:
Xpand completed.
Execution mode: Line.
Examples
The following is a legal abbreviation which may be used with the XPAND
command and its parameters:
X100 Increase the file limit size of the current work file by 100
records.
In the example, a KSAM file is created with a maximum number of 3 records
(1). An attempt to LIST the complete contents of the file results in an
error message because, at this point, the file is empty (2). A second
error is caused by an attempt to enter more records into the file than
were specified as the maximum number previously (3). The XPAND command
is used to expand the maximum number of records the file will accept by
ten (4). When the ADD command is again employed, the file accepts the
additional records (5).
