Program Samples

Person This sample is uses the graphical SCREEN SECTION  demonstrating menu, push buttons and the display of jpg pictures in a graphical program.  To execute this sample you must download to a local machine. CallJava illustrates a COBOL program calling java. COBOLCallingCOBOL This sample is a COBOL program calling a COBOL subprogram and passing parameters in both directions.  Parameters include alphanumeric, numeric, binary, group, and java objects.   The default passing convention is BY REFERENCE, not BY VALUE. That means that  the address of the parameter is passed, not the actual literal value. CallCobol2 illustrates PERCobol calling an HP COBOL II on MPE/iX. A descriptive text describes this sample. Demo Server illustrates a COBOL application running multiple threads and supporting any number of clients.  Client and Server JBOSS sample illustrates building an Enterprise Java Bean with PERCobol.  Enterprise JavaBean Guide  documentation will aid in understanding the creation and deployment of EJBs using PERCobol. Graphics illustrates using the graphic SCREEN SECTION elements for building platform independent GUIs. An executable sample is available at http://www.legacyj.com/samples/graphics.html Grid illustrates a COBOL application that will calculate data by rows and columns Register illustrates a COBOL servlet that accepts customer data and stores the results in a COBOL file. This example also illustrates dynamic html. Windows is a single program which demonstrates the use of multiple windows. Creating a new window at the beginning of a subprogram and destroying the window when done, control will revert back to the existing window. (You can use LINE and COLUMN for the DISPLAY creating the window to do positioning.) SQLCursors  illustrates SQL Cursors with LegacyJ PERCobol. PL/SQL illustrates PL/SQL with LegacyJ PERCobol. CICS LINK Sample using LegacyJ PERCobol and Transaction Platform COBOL to LTP Linker Sample to illustrate LINKing from a Batch COBOL application to an online LTP application. (Download includes companion documentation. LTP SQL JMS Sample for LTP, CICS START (i.e., JMS), & SQL using DriverManager LTP SQL JMS Sample for LTP, CICS START (i.e., JMS), & SQL using DataSource. SQL-JAVA-COB Sample illustrates a java program that updates an SQL row in an SQL table, then calls a COBOL program to displays the row, updates and row to then goback to the java program, which in turn displays the row. The java program passes a SQL connection. JSP COBOL Sample of COBOL program with JSP web interface.
