<p>Further considerations of the ways to specify the PRINT keyword
|
|||
|
|
are discussed in the following sections.</p>
|
|||
|
|
<p>If you specify the PRINT keyword
|
|||
|
|
in any form, the workstation user can print a display containing the message
|
|||
|
|
help. In this case, the print operation is performed as if the PRINT keyword
|
|||
|
|
were specified with no parameters.</p>

on the PRTFILE parameter on the CRTDEVDSP or the CHGDEVDSP command that is
|

|

used to describe the display device to the system.</p>
|

|
|
<p>For workstation printers

attached through the workstation controller, a message indicating that there
|

is a problem is sent to the workstation user requesting the print function.
|

The workstation user can make the printer ready or press the Reset key. To
|

cancel a print request before it is complete, the workstation user can press
|
|||
|

and hold the Shift key, then press the Print key.</p>

returns control to your program with the specified response indicator set

program sends another output operation to the display file. There is no difference

<p>The

<div class="example"><h4 class="sectiontitle">Example: PRINT keyword with a specified printer file</h4><p>The <span class="keyword">i5/OS</span> program reads the display

buffer and prints the display image using the specified printer file. The

printer file that you specify as a parameter value for this keyword can be
|

either an externally described or a program-described file. It also can be

either spooled or nonspooled. If you specify an externally described printer

file, it must contain a record format with the same name as the file.</p>

|
<p>The

printer file must exist and be authorized to the user of the display when

the Print key is pressed. This also applies to the library name if it is specified.

If the <span class="keyword">i5/OS</span> operating

system is unable to perform the print function on the specified printer file,
|

it attempts to use the printer file specified on the PRTFILE parameter of

the CRTDEVDSP or the CHGDEVDSP command. SPOOL(*YES) should be specified on

the CRTPRTF or CHGPRTF command to prevent the keyboard from locking.</p>
