BeginProg, EndProg (Begin Program, End Program)

The BeginProg instruction is used to mark the beginning of a program. EndProg marks the end of a program.

Syntax

BeginProg

      ...

      ...

EndProg

The following code shows the layout of a typical datalogger program and the use of the BeginProg/EndProg statements. Program variables and the Data table are defined, followed by the code for the main program.

'Declare public variables
Public Ptemp, Batt_volt

'Define Data Tables
DataTable (Test,1,-1) 'Set table size to # of records, or -1 to autoallocate
  DataInterval (0,15,Sec,10)
  Minimum (1,Batt_volt,FP2,False,False)
  Sample (1,Ptemp,FP2)
EndTable

 

'MainProgram
BeginProg 'main program begins
  Scan (1,Sec,0,0) 'scan at 1 second intervals in an infinite loop
    PanelTemp (PTemp,60) 'read temperature of the datalogger wiring panel in degrees Celsius
    Battery(Batt_volt) 'read the voltage of the battery powering the datalogger in volts
    'Enter other measurement instructions 
    'Call Output Tables
    CallTable Test
  NextScan 'scan again

EndProg 'main program ends

Remarks

All of the instructions for the main program fall between the BeginProg and EndProg statements. Program Variables, Data tables, and Subroutines must be defined before the main program.
