|
<p><strong>Bytes available.</strong> The length of all data available for the

|
|
requested format. All available data is returned if enough space is
|
||
|
|
provided.</p>
|
||
|
|
|
||
|
|
<p><strong>Bytes returned.</strong> The length of all data actually returned.
|
||
|
|
If the receiver variable is not large enough to hold the data, no other data is
|
||
|
|
returned and this value is less than the bytes available.</p>
|
||
|
|
|
||
|
|
<p><strong>Length of prompt override command string.</strong> The length of the
|
||
|
|
prompt override command string returned by the API. If the prompt override
|
||
|
|
program completed normally, but did not return a command string, this will be
|
||
|
|
0. If the prompt override program ended in error, this will be -1.</p>
|
||
|
|
|
||
|
|
<p><strong>Offset to prompt override command string.</strong> Offset to the
|
||
|
|
first byte of the prompt override command string.</p>
|
||
|
|
|
||
|
|
<p><strong>Prompt override command string.</strong> The command string returned
|
||
|
|
by the prompt override program. The command string will not include the command
|
||
|
|
name, the key parameters, or any other parameters not specified by the prompt
|
||
|
|
override program. If the receiver is not large enough to hold the entire
|
||
|
|
command string, the command string will not be returned, and the Bytes
|
||
|
|
available field will have the size of the receiver value required for the
|
||
|
|
command string.</p>
|
||
|
|
|
||
|
|
<p><strong>Prompt override program library name.</strong> The name of the
|
||
|
|
library in which the prompt override program was found.</p>
|
||
|
|
|
||
|
|
<p><strong>Prompt override program name.</strong> The name of the prompt

|
override program that was called to supply the prompt override command
|

|
|
string.</p>
