<h1 class="topictitle1">Receive data from a database file</h1>
|

|
|
<div><p>The only command you can use to receive data from a database file
|
||
|
|
is the <span class="cmdname">Receive File (RCVF)</span> command.</p>
|
||
|
|
<div class="section"> <p>When you run a <span class="cmdname">Receive File (RCVF)</span> command,
|
||
|
|
the next record on the file's access path is read, and the values of the fields
|
||
|
|
defined in the database record format are placed in the corresponding CL variables.
|
||
|
|
Note that CL does not support zoned decimal or binary numbers. Consequently,
|
||
|
|
fields in the database file defined as zoned decimal or binary cause *DEC
|
||
|
|
fields to be defined in the CL procedure or program. *DEC fields are internally
|
||
|
|
supported as packed decimal, and the <span class="cmdname">Receive File (RCVF)</span> command
|
||
|
|
performs the conversion from zoned decimal and binary to packed decimal as
|
||
|
|
required. Database files which contain floating point data cannot be used
|
||
|
|
in a CL procedure or program.</p>
|
||
|
|
<p>When the end of file is reached, message
|
||
|
|
CPF0864 is sent to the procedure or OPM program. The CL variables declared
|
||
|
|
for the record format are not changed by the processing of the <span class="cmdname">Receive
|
||
|
|
File (RCVF)</span> command when this message is sent. You should monitor
|
||
|
|
for this message and perform the appropriate action for end of file. If you
|
||
|
|
attempt to run additional RCVF commands after end of file has been reached,
|
||
|
|
message CPF0864 is sent again.</p>
