The Modify: Erase File Node
After you have uploaded data from the portable file, you will want to erase its
contents. Otherwise, further data you collect is appended to the data you just
uploaded, and your data file will quickly grow out of control. Complete the
following steps:
1. Select the
Modify: Erase File
node to open its dialog box.
2. On the
Data to Modify
tab, select
File
in the
Data Destination
pull-
down list.
3. Select
Monthly Inventory
from the
File
pull-down list.
4. On the
Modification type
tab, select
Delete
from the pull-down list.

5. On the
Next Node
tab, select
Exit Main Menu
from the pull-
down list.
6. Press
OK
to save your settings and exit the dialog.
The nodes for uploading data are now complete. Close the
Upload Frame to
return to the main program level. Then select
File > Save
to save your changes
to the file.
The nodes that you created for the
Upload Data
frame ask the user for confir-
mation of the upload task. If the user answers
Yes
, it outputs the data file
over the serial port. If the upload is successful, a message is displayed, the por-
table’s file is cleared, and the
Main Menu
returns. If the upload is unsuccessful,
the program beeps, displays an error message, and gives the user the option of
trying again.
Your portable program should now be complete.
