.. PCP.MEX: MAIN PCP SCRIPT (04/15/90)
..
.. This is the main entry point to the script for automating
.. calls via the PC-Pursuit network.  This part of the script
.. handles initialization of MEX and the modem and establishes
.. the connection to the local access number.

.. Two things we have to take care of right away

..	Initialization
..
.. ------------------------------------------------------------

.. Initialize data from command line.  There are three optional
.. parameters.  The first is a menu selection number to call
.. immediately.  The second is the number of attempts that
.. should be made to connect to the destination city.  The third
.. is the number of times to attempt to connect to the local
.. number in that city.  In all cases, we check to make sure that
.. we have an acceptable value.

.. menu selection (variable %m)

%d={1:0};.           read parameter 1 with default value of 0
if %d<1 GOTO BAD1;.  ignore if illegal value
if %d>100 GOTO BAD1
%m=%d;.              if value in range 1..100, use it
LABEL BAD1

.. similar code for other parameters omitted.

.. Initialize various variables and MEX parameters

%a=0;.               no area code requested
.. etc.
D=" ";.              no PCP outdial (city) code
.. etc.

stat filter on       turn filter on
stat trigger "";.    do sendouts immediately
stat sodelay on;.    ..but at a slow rate
stat reply 0;.       do not wait for response to a sendout
stat case on;.       ignore case
.. etc.
