TOP: Q Sets an uppercase Q as the high end of the Picked range.
With these limits, the subfile will contain entries from
field 5 that start with My through Qy.
RC FM
Displays any record. You can also use the RC (ReCord) command to enter
information into a record. The RC command displays the record whose record
number you give in the command. You can display a filled record or an empty
record. Unlike the RV (ReView records) command, which displays all the records
in a series, the RC command displays only one specific record. Once the record is
displayed, you can make changes if you like.
When you display an empty record, you can enter information into it. Unlike
entering records with the NR (Next Record) command, the RC command does
not automatically move to the next record after each record is entered. Use RC
when you are entering just a few records at a time, and use NR when you are
entering a series of records.
To use the RC command to display a record, type RC and the record number
of the record you want to display followed by a semicolon.
To use the RC command to enter a record, follow these steps:
1. Issue a TF command to display the record number of the last record entered if
you are adding records to a previously stored file.
2. Issue an RC command to display the first record you are going to enter. If you
are entering records into a new file, the first record would be RC1;, and if you
are adding records to an old file, the first record would be 1 plus the record
number named in the TF command as the last record entered.
3. Store the first record with the UD (UpDate record) command.
4. Issue another RC command to enter the next record. You must enter another
RC command for each record you enter.
5. Store each record with the UD (UpDate record) command.
Example: rc3; Displays record number 3, which may or may not be a filled record.
You can view it or change it if it is filled, or you can enter informa
tion if it is not filled.
RESETLIST FM
Cancels any type of subfile. The RESETLIST command disbands sorted
subfiles, searched subfiles, and subfiles set by the HIGHRC or PI (Pick) com
mands. RESETLIST has no effect on the contents of the records; it is NOT like
the spreadsheet RESET command.
