Inserting the data into 3 levels (0,1,2,3 levels) into database from flat file using Application Engine

Inserting the data into 3 levels (0,1,2,3 levels) into database from flat file using Application Engine Below is the sample code (Ive used 2 fields in all the 3 levels)

Level0 -> Organisational ID, Organisational Name
Level1 -> College ID, College Name
Level2 -> Department ID, Department Name
Level3 -> Employee ID, Employee Name, Age

Local Record &R0, &R1, &R2, &R3;

&R0 = CreateRecord(Record.A_ORG_TBL);
&R1 = CreateRecord(Record.A_COL_TBL);
&R2 = CreateRecord(Record.A_DEPT_TBL);
&R3 = CreateRecord(Record.A_EMPL_TBL);

&myfile = GetFile("C:\temp\phani.txt", "R", %FilePath_Absolute);
&myfile1 = GetFile("C:\temp\pha.txt", "W", "A", %FilePath_Absolute);
&myfile1.writeline("empty array creation");
