ELDE can be invoked by the user with the following commands and macros:
The START-EXECUTABLE-PROGRAM or LOAD-EXECUTABLE-PROGRAM command if the FROM-FILE operand has been specified with a file name or if the module to be loaded is a load module.
The START-PROGRAM or LOAD-PROGRAM command if the FROM-FILE operand has been specified with a file name or with *PHASE.
The START-PROGRAM and LOAD-PROGRAM will only be supported for compatibility reasons. For new applications the START-EXECUTABLE-PROGRAM or LOAD-EXECUTABLE-PROGRAM should be used.The LPOV macro, which dynamically loads overlay segments. The CALL and SEGLD macros implicitly cause the execution of the LPOV macro.
The detailed description of the commands can be found in the „Commands“ manual [5].
