Python



BEGIN
For L1 := 1 to (NumRecFields) DO
	IF NOT EOLN(LoadFile) THEN Read(gChosenFields[L1]);
NumSelected := 0;
{Now we need to load the linking into the dialog fields}
For L2 := 1 to (NumRecFields) DO {Load all but the unique ID Field into the dialog}
	BEGIN

BEGIN
   	NumOfFields := 0;
   	Open(TheFile);
   	While Not EOLN(TheFile) DO
	{Fix this procedure so that it works correctly and actually loads in empty fields correctly
		Currently the read command does NOT treat consecutive delimeters correctly}
   		BEGIN
			NumOfFields := NumOfFields + 1;
			Read(TmpString);
			IncomingFieldNames[NumOfFields] := TmpString;
    	END;


result = vs.EOLN('file.txt')
