Creating & Using Nodes
58 PT Program Generator (PPG) v5.0
Input From Tab (Next Nodes)
For each selected input source, specify the frame or node to branch to. The
pull-down list for this option lists each node in the frame or subroutine. Select
the next node to be completed for each input type. You can specify a different
Link for each type of source. For example, you could Link any scanned (scan-
ner) input to a
Verify node that makes sure it's a valid number and at the same
time set up any function key input to return to the Main Menu. You can also
specify a file or register to store the input data in, create a Link for a timeout
condition (no input received within a given number of seconds), and arrange
for input data to be displayed in a specific position on the screen.
Track Size Tab
The Track Size tab option specifies whether to save the number of characters
received. Selecting this option allows you to select a register (refer to
Registers
on page 78). Be sure to use a different register from the one used to store the
data. For serial input with a file as the destination, the number of records in
the file is saved as the size in the register.
Scanner Allows data input from the bar code scanner. The program proceeds without
waiting for the user to press the
ENTER key.
Data Key Allows data input from the portable’s data keys (all the keys except the four
function keys,
<F1> through <F4>). The program waits for the user to press
the
ENTER key.
<Fn> Key Allows data input from any of the function keys. There are four function keys,
<F1> through <F4> or you can press the <Shift> key once to put the unit
into shifted mode. This results in function keys
<F5> through <F8>.
For example, press shift and then <F3> to enter <F7>. The program pro-
ceeds without waiting for the user to press the
ENTER key.
Serial Allows data, such as downloaded inventory, to be input using the serial inter-
face or serial device.
On Error For each selected node, specify a frame or node to branch to upon receiving
an error.
TimeOut Specifies the number of seconds the portable will wait for data to be input. If
no response is encountered within that time, the program moves on to the
node specified by the
Link To setting.
