Using an "Include" File
'This program example demonstrates the use of an 'include' file. An 'include' file is a
CRBasic file that usually
'resides on the CPU: drive of the CR800. It is essentially a subroutine that is
'stored in a file separate from the main program, but it compiles as an insert to the main
'program. It can be used once or multiple times, and by multiple programs.
''Include' files begin with the SlowSequence instruction and can contain any code.
'
'Procedure to use an 'include' file in this example:
'1. Copy the code from the CRbasic example 'Include' File to Control Switched 12 V
(p. 112)
to
' CRBasic Editor, name it 'IncludeFile.cr8, and save it to the same PC folder on which
' resides the main program file (this make pre-compiling possible. Including the
' SlowSequence instruction as the first statement is required, followed by any other code.
'2. Send the 'include' file to the CPU: drive of the CR800 using the File Control menu
' of the datalogger support software
.
Be sure to de-select the Run Now and Run On
' Power-up options that are presented by the software when sending the file.
'3. Add the Include instruction to the main CRBasic program at the location from which the
' 'include' file is to be called (see the following code).
'4. Enter the CR800 file system path and file name after the Include() instruction, as shown
' in the following code.
'
'IncludeFile.cr8 contains code to control power to a cellular phone modem.
'
'Cell phone + wire to be connected to SW12 terminal. Negative (-) wire
