The Built-in Software
You enter the maximum number of characters to be entered in field 1. The
default is 1 and the maximum is 38. Just type over the 01 to select a number.
Again, the trailing semicolon is required.
The third and fourth prompts are repeated for each field until the total number
of fields (entered at the second prompt) are defined.
When you finish entering all the fields, the screen clears and a review of the file
design is displayed. A message telling you how many records you can store (999)
for the file is also displayed.
The computer also asks OK TO FORMAT DISK? Y/N. You should have a
new, blank disk ready. Insert it in the disk and type Y in response to the prompt
question. The formatting procedure takes a short time. When the computer
reports that the disk is ready, your new file design is stored on it. You are then
ready to enter records.
Example: newtf Tells the file manager that you are ready to design a new file.
NR FM
Enters information into records. Unlike entering records with the RC
(ReCord) command, the NR (Next Record) command automatically moves to
the next record after each record is entered. The NR command saves time, and
you should use it instead of RC when you are entering a series of records.
To use the NR command, 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 an NR command to enter subsequent records. NR displays the next
record automatically.
5. Store each record with the UD (UpDate record) command.
6. Terminate the NR command by entering command mode and issuing a
command.
Example: nr Displays a series of records so you can quickly enter information.
