The program’s first task is to load the subfile with one page of records (in this case, nine). This code is shown in Figure Notice that each time a record is read from the data file, the RCVQUE subroutine is executed. For the initial subfile load, this subroutine won’t accomplish any-thing— (I will explain this later). The following example is an OPM RPG program that loads the subfile one page at a time.
