SETFL (Set File Load Mode) Macro
The macro causes ISAM to set up the file so that the load or extension function can be performed.
This macro must be issued whenever the file is loaded or extended.
When loading a file, SETFL pre-formats the last track of each track index. When extending a file, SETFL pre-formats only the last track of the last track index plus each new track index for the extension of the file. This allows prime data on a shared track to be referenced even though no track indexes exist on the shared track.

- The name of the file to be loaded is the only operand that is required for this macro. The name that you specify is the same you used for the DTFIS macro, which defines the file. This name can be specified as a symbol or in register notation. Register notation is necessary if your program is to be self-relocating.
