TableName.Record (Determine DataTable Record Number)

The TableName.Record syntax is used to determine the record number of a specific DataTable record.

Syntax

TableName.Record(1,n)

This example program uses the TableName.Record syntax to put a filemark in the DataTable every 100 records.

Public Heater         
Units Heater = Deg_F      

Public Flag           
Dim TRef            
Public RecData

DataTable(MAIN,True,-1)  
  DataInterval(0,50,msec,100) 
  Sample(1,Heater,FP2)
EndTable

BeginProg 
  Scan(50,msec,0,0)   
   
    PanelTemp(TRef,4000)       'RefTemp,Integrate
    TCDiff(Heater,1,mv34,1,TYPET,TRef,False,0,4000,1.8,32)
    CDM_PanelTemp (VOLT116,CPI_BusA + 1,TRef,1,1,4000)  
    CDM_TCDiff(VOLt116, CPI_BusA + 1, Heater,1,mv34,1,TYPET,TRef,False,0,4000,1.8,32)

    CallTable MAIN               

    RecData = Main.record(1,1)     'RecData = record # of current record
    If RecData Mod 100 = 0 Then    'Conditional to put a filemark every 100 records
      FileMark(Main)
      Flag = -1
    Else
      Flag = 0
    EndIf

  NextScan             
EndProg

Remarks

This syntax returns the record number of the specified number of records prior to the current record. The name of the DataTable is entered in place of the TableName parameter. TableName is limited to 20 characters. The number of records to go back in the DataTable is specified by n.
