Parenthases

[sv806]

a couple codes i found in the help file for pbasic, i was wondering if the ( ) are needed in the first code? and what is bin1 in7, CR do?




Setup:
INPUT 4

Hold:
IF (IN4 = 0) THEN Hold ' Stay here until P4 is 1



---------------------------------------------------------------------



Main:
INPUT 7 ' Make P7 an input
DEBUG "State of P7: ",
BIN1 IN7, CR

OUT7 = 0 ' Write 0 to output latch
DEBUG "After 0 written to OUT7: ",
BIN1 IN7, CR

OUTPUT 7 ' Make P7 an output
DEBUG "After P7 changed to output: ",
BIN1 IN7
END

BIN1 IN7, CR is part of the debug statement above it. DEBUG outputs data to the computer on the serial port in this case it prints "State of P7: <binary value of pin7> <carrige return>
IN7 is the input value of pin7
