I'm opening an MPE message file using MPE Class file to read in about a byte
steam of 3385 bytes for further processing. My POSIX shell was started as:

run sh.hpbin.sys;info="-L" ;NMSTACK=90000000



Source listing e.g.
........
.........

 MPEFile myfile = new MPEFile("DAN1000D");
 myfile.setDomain(MPEFile.DOMAIN_OLD);
 myfile.setAccess(MPEFile.ACCESS_READ); /* unnecessary; is default */

 System.out.println("About to Open input file");
 /* Open input file for processing */
 try {
       myfile.open();
 } catch (MPEException e) { e.printStackTrace(); }
 if (myfile.getFileNum() == 0) {
      MPEStatus status = myfile.getStatus();
      System.out.println("HPFOPEN Status: subsys " + status.getSubsys() +"
info " + status.getInfo() );
    } else {
       System.out.println("Opened file # " + myfile.getFileNum() );
        int cnt = 0;

    while (true) {
       try {
        /* set None Destructive read mode on the message file */
        setNoneDestructiveRead(myfile.getFileNum());

        /* Read Input Stream */
        myfile.read(3385);
        cnt +=1;
        } catch (MPEException e) { e.printStackTrace(); }
        if (myfile.eof()) break;

        ByteArrayInputStream bais = new
ByteArrayInputStream(myfile.getBuffer());

        bais.read(TRANS,0,6);
        bais.read(DATE,0,8);
        ...
