Using FUP for Advanced File Management
For example, you can reset more than one parameter with a single RESET command by
separating the parameters with commas:

EXT ( 5 PAGES, 5 PAGES )
REC 80
BLOCK
4096
IBLOCK 4096
KEYLEN 9

TYPE K
EXT ( 1 PAGES, 1 PAGES )

To reset all file-creation parameters at once, enter RESET with no parameters. For
example, this command restores all the file-creation parameters to their default values:
-RESET
-SHOW

File-Creation Examples
These examples show how to create all the types of files: unstructured, entry-sequenced,
relative, and key-sequenced files. Examples are also given for creating files with
alternate keys, partitioned files, and files that match the attributes of an existing file.
Each example shows the series of commands needed.
Creating an Unstructured File
Unstructured files are arrays of bytes. They are normally used to store object programs
or text created with a text editing program such as TEDIT. If you create a file that has
the logon default file-creation attributes, the new file is an unstructured file.
