Use of the Disable Variable
'This program example demonstrates the use of the 'disable' variable, or DisableVar, which
'is a parameter in many output processing instructions. Use of the 'disable' variable
'allows source data to be selectively included in averages, maxima, minima, etc. If the
''disable' variable equals -1, or true, data are not included; if equal to 0, or false,
'data are included. The 'disable' variable is set to false by default.
'Declare Variables and Units
Public Oscillator As Long
Public Flag(1) As Boolean
Public DisableVar As Boolean
'Define Data Tables
DataTable(OscAvgData,True,-1)
DataInterval(0,1,Min,10)
Average(1,Oscillator,FP2,DisableVar)
EndTable
'Main Program
BeginProg
Scan(1,Sec,1,0)
'Reset and Increment Counter
If Oscillator = 2 Then Oscillator = 0
Oscillator = Oscillator + 1
'Process and Control
If Oscillator = 1
If Flag(1) = True Then
DisableVar = True
EndIf
Else
DisableVar = False
EndIf
'Call Data Tables and Store Data
CallTable(OscAvgData)

EndProg
Numbers of Records
The exact number of records that can be stored in a data table is governed by a
complex set of rules, the summary of which can be found in Memory Cards and
Record Numbers.
