Transferring Data
There are several tools for moving data into or out of paths.
GETCH
and
PUTCH do a byte at a time. PRINT and ENTER move formatted ascii data
between paths and LPL variables.
BPRINT
and
BENTER
move the values
of LPL variables in binary form to and from paths. XFER transfers data from
one path to another, and (depending on what type of paths are involved) can
do it
simultaneously with LPL program execution. For example, with an over-
lapped
XFER
, a file can be sent out the comm port at the same time that mea-
surements are being taken. As an example of data transfers, consider
Figure 23-21, a simple terminal emulator program.
:FCT Main
{
Open a path to the display.
OPEN_LCD IF RETURN THEN
:PTR disp
Define 8 column tabs.
"T8" disp CONVERTIN
Send some data with imbedded tabs to ÕdispÕ.
"123456781234567812345678\nabc\tdef\tghi" disp PRINT
GETKEY DROP
Close the path ÕdispÕ.
disp CLOSE
