<div><p>In this example, the copy command copies records in the file EMP1
|

|
to the file EMP1T. EMP1T is a file in a test library. Because you only need
|
||
|
|
a subset of the records, you specify a from-key value and a to-key value. Both are full key values. </p>
|

<div class="section"><div class="p"> Note that a 1 specified in the FROMKEY and TOKEY parameters indicates
|
||
|
|
the number of key fields to be used in searching the record keys, starting
|
||
|
|
with the first key field. <pre>CPYF FROMFILE(PERSONNEL/EMP1) +

is shorter than the key field length, it will be padded on the right with

zeros. Thus, a 5-position key field specified as FROMKEY(1 8) causes a search
|

for a key equal to hex F800000000. If the key value contains blanks or special

characters, you must enclose them in apostrophes.</p>
