Mode: COMMAND and/or RUN
Type: INPUT/OUTPUT
The PH0. and PH1. statements function the same as the PRINT statement
except that the values are printed out in a hexadecimal format. The PH0.
statement suppresses two leading zeros if the number printed is less than
255 (0FFH). The PH1. statement always prints out four hexadecimal digits.
The character “H” is always printed after the number when PH0. or PH1. is
used to direct an output. The values printed are always truncated integers.
If the number printed is not within the range of valid integer (i.e. between
0 and 65535 (0FFFFH) inclusive), the BASIC Module defaults to the
normal mode of print. If this happens no “H” prints out after the value.
Since integers are entered in either decimal or hexadecimal form the
statements PRINT, PH0., and PH1. are used to perform decimal to
hexadecimal and hexadecimal to decimal conversion. All comments that
apply to the PRINT statement apply to the PH0. and PH1. statements.
PH0.# and PH 1.# function the same as PH0. and PH1. respectively, except
that the output is directed to the list device instead of the console device.
The baud rate and peripheral port parameters must match your device. See
