Chapter 20 Database (OPTION) Technical Reference Manual
6 NEXT ROW:
a. <ENTER> key alone:
The "NEXT ROW" command will cause the very next
row of the currently selected DATABASE to be recalled.
This operation can be quite useful when used following
the "FIRST ROW" command to allow every stored row
to be sequentially recalled and processed in some
manner. An example might be to print out a report using
the custom transmit setups in a format which would not
be possible with the standard printout.
b. An entry followed by the <ENTER> key:
An entry preceding the "NEXT ROW" command is not
defined and will result in an "ENTRY ERROR"
message.
7 NEXT MATCH:
a. <ENTER> key alone:
This command operates the same as the "RECALL
ROW" command except that the search for the matching
record begins with the record following the last accessed
record. Specifically, the next row which matches the
current data in the parameter which corresponds to the
currently selected column in the currently selected
DATABASE is located. Then all the other information
in that row is copied into the corresponding parameters.
This command would be used successively following a
"RECALL ROW" command. It allows multiple
occurences of the same data to be located and processed.
For example, every occurence of a transaction which
involved a specific part number could be recalled and
printed.
b. An entry followed by the <ENTER> key:
This form of the "NEXT MATCH" command operates
similar to the entry version of the "RECALL ROW"
command except that the search for the matching record
begins with the record following the last accessed record.
In effect this operates the same as the "NEXT MATCH"
command without an entry except that the data being
searched for is the entered data.
8 CLEAR ROW:
a. <ENTER> key alone:
The "CLEAR ROW" command is used to delete a stored
row from memory. When invoked without an entry this
command will delete the last accessed row from the
currently selected database. However, before deleting
the row from memory, the warning message
"SURE? ?????" is displayed. Pressing the <ENTER>
key again will proceed with the command and delete the
row from memory. Pressing any other key abort the
deletion. This command would normally be used in
applications where information is only temporarily
stored in the database, such as keeping track of all the
item numbers which are currently undergoing a
particular process. After that process were completed,
then the rows could be deleted.
b. An entry followed by the <ENTER> key:
This form of the "CLEAR ROW" command allows the
row which is to be deleted to be specified at the time of
the deletion. The data entered before pressing the
<ENTER> key is the value to search for to locate the
row to be deleted. Again, the warning message
"SURE? ?????" will be displayed and pressing the
<ENTER> key will proceed with the deletion.
9 CLEAR COLUMN:
a. <ENTER> key alone:
The "CLEAR COLMN" command may not be invoked
without a numeric entry. If it is invoked without an
entry, the "ENTRY ERROR" message will result.
b. An entry followed by the <ENTER> key:
The "CLEAR COLUMN" command allows a particular
column of a database to be cleared. If the column is a
numeric type then the numeric values for that column in
each row are set to zero. For alpha numeric types the
data is set to be blank. The entered number is the
parameter ID of the column which is to be cleared.
Again, the warning message "SURE? ?????" will be
displayed and pressing the <ENTER> key will proceed
with the clearing of the column.
This command may be useful in applications such as
where the accumulated weight must be deleted
periodically. This allows for the total amount of a
product which is produced on a shift to be totalized and
printed and then cleared for the next shift.
