Section 4. The File Manager 147
Because RESETLIST restores the file to its original organization, you should
use it before you create a subfile when you want to be sure a previous subfile does
not affect your current project.
Example: resetlist Restores the file to its original organization by canceling a
subfile.
RV FM
Displays the records in order. If the file has been reorganized into a subfile, the
records are displayed in subfile organization with the actual record number also
displayed on the screen. The RV (ReView) command starts with the record whose
number you give in the command and continues through the file, displaying each
record quickly.
To speed up the review, press the space bar. To slow it down, press the S key.
To end the review, press the Q key.
Use the RV command to make a quick review of a new file or a newly created
subfile or to scan for a particular record whose number you do not remember. To
use the RV command, type rv and the number of the first record you want to
review, followed by a semicolon.
Examples: rvl; Quickly displays all the records in the file or subfile, starting at
record 1.
rv25; Starts the review at record 25.
SR FM
Looks through records to find those that contain data you specify. You can
search for any letters or numbers up to 38 characters in length. The SR (SeaRch)
command searches every field; the search is for a character match rather than for
the contents of a specific field. In other words, the SR command does not search
just one field in each record. The search criteria cannot spread into two fields. For
example, if you are searching for New York and the words New and York appear
in separate fields in a record, this is not considered a match.
To use the SR command, type sr and,press RETURN. When the prompt
SEARCH is displayed, type the characters you want to find in the records. Unlike
the PI (Pick) command, the SR command does not distinguish between upper
and lower case letters, so Computer and computer are considered equal.
If there is no subfile, the SR command begins its search with record 1 and
sequentially investigates every record in the field. If there is a subfile, the SR
command searches records according to the organization of the subfile.
As a search executes, each record that contains a match is displayed. The
message CONTINUE Y/N is also displayed. If you want to continue searching
for more instances of a match, type Y. If you want to abort the search, type N.
