<div><p>This example shows how to create a new physical file with the same
|
||
|
|
name in a different library.</p>
|
||
|
|
<div class="section"> <ol><li>Create a new physical file with a different record format in a library
|
||
|
|
different from the library the old physical file is in. The name of the new
|
||
|
|
file should be the same as the name of the old file. (The old physical file
|
||
|
|
FILEPFC is in library LIBB and has two members, MBRC1 and MBRC2.) <pre>CRTPF FILE(NEWLIB/FILEPFC) MAXMBRS(2)...</pre>
|
||
|
|
</li>
|
||
|
|
<li>Copy the members of the old physical file to the new physical file. The
|
||
|
|
members in the new physical file are automatically named the same as the members
|
||
|
|
in the old physical file because TOMBR(*FROMMBR) and FROMMBR(*ALL) are specified. <pre>CPYF FROMFILE(LIBB/FILEPFC) TOFILE(NEWLIB/FILEPFC)
|
||
|
|
FROMMBR(*ALL) TOMBR(*FROMMBR)
|
||
|
|
FMTOPT(*MAP *DROP) MBROPT(*ADD)</pre>
|
||
|
|
</li>
|
||
|
|
<li>Describe and create a new logical file in a library different from the
|
||
|
|
library the old logical file is in. The new logical file name should be the
|
||
|
|
same as the old logical file name. You can use the FORMAT keyword to use the
|
||
|
|
same record formats as in the current logical file if no changes
|
||
|
|
need to be made to the record formats. You can also use the Create Duplicate
|
||
|
|
Object (CRTDUPOBJ) command to create another logical file from the old logical
|
||
|
|
file FILELFC in library LIBB. <pre>CRTLF FILE(NEWLIB/FILELFC)</pre>
|
||
|
|
</li>
|
||
|
|
<li>Delete the old logical and physical files. <pre>DLTF FILE(LIBB/FILELFC)
|
||
|
|
DLTF FILE(LIBB/FILEPFC)</pre>
|
||
|
|
</li>
|
||
|
|
<li>Move the newly created files to the original library by using the following
|
||
|
|
commands:<pre>MOVOBJ OBJ(NEWLIB/FILELFC) OBJTYPE(*FILE) TOLIB(LIBB)
|
||
|
|
MOVOBJ OBJ(NEWLIB/FILEPFC) OBJTYPE(*FILE) TOLIB(LIBB)</pre>
