by using -p <outfile name>.  This feature allows the smallest size program file 
possible to be sent to the CR1000, which may help keep costs down over very 
expensive telecommunication links. 
CRBasic example Conditional Code 
(p. 181) shows a sample program that 
demonstrates use of conditional compilation features in CRBasic.  Within the 
program are examples showing the use of the predefined LoggerType constant 
and associated predefined datalogger constants (6, 800, 1000, and 3000). 
 
 
CRBasic Example 29.  Conditional Code 
'This program example demonstrates program compilation than is conditional on datalogger 
'model and program speed. Key instructions include #If, #ElseIf, #Else and #EndIf. 
 
'Set program options based on: 
'  LoggerType, which is a constant predefined in the CR1000 operating system 
'  ProgramSpeed, which is defined in the following statement: 
Const ProgramSpeed = 2 
#If ProgramSpeed = 1 
 Const ScanRate = 1               '1 second 
 Const Speed = "1 Second" 
#ElseIf ProgramSpeed = 2 
 Const ScanRate = 10              '10 seconds 
 Const Speed = "10 Second" 
#ElseIf ProgramSpeed = 3 
 Const ScanRate = 30              '30 seconds 
 Const Speed = "30 Second" 
#Else 
 Const ScanRate = 5               '5 seconds 
 Const Speed = "5 Second" 
'Public Variables 
Public ValueRead, SelectedSpeed As String * 50 
 
'Main Program 
BeginProg 
 
 'Return the selected speed and logger type for display. 
 #If LoggerType = 3000 
 SelectedSpeed = "CR3000 running at " & Speed & " intervals." 
 #ElseIf LoggerType = 1000 
 SelectedSpeed = "CR1000 running at " & Speed & " intervals." 
 #ElseIf LoggerType = 800 
 SelectedSpeed = "CR800 running at " & Speed & " intervals." 
 #ElseIf LoggerType = 6 
 SelectedSpeed = "CR6 running at " & Speed & " intervals." 
 #Else 
 SelectedSpeed = "Unknown Logger " & Speed & " intervals." 
 #EndIf 
 'Open the serial port 
 SerialOpen(ComC1,9600,10,0,10000) 
 
 'Main Scan 
 Scan(ScanRate,Sec,0,0) 
 'Measure using different parameters and a different SE channel depending 
 'on the datalogger type the program is running in.
