# y (update stamping) processing code

The y processing code stamps user, PIB,
and/or time/date update information into an internal item header from
all processors.

If you attempt to file or restore an update stamp in an
FSI file-defining item, it will be commented-out with an asterisk
(*).

This processing code is supported only
from the VME.

| System Processors | N/A |
| --- | --- |
| Code Type | File Defining |
| Dictionary Attributes | Correlative |

## Syntax

```
y{u}{p}{t}
```

## Parameter(s)

To be effective, the y code must be followed by one or more of these letters
to stamp information at update time:

| u | User-ID. |
| --- | --- |
| p | User PIB. |
| t | Time/Date information. The hexadecimal Time/Date indicates the number of seconds since 12/31/67. |

## Description

Unlike the x code, the y code updates stamp information when
an item is updated from any processor. Additionally, this stamp information
is stored outside the normal item body in a special textual header.

To read the stamp information generated by the y code, prefix the file name with the word hdr:. The header information
can then be examined from FlashBASIC, AQL, or any other processor.
Note that the stamp information *cannot* be written outside of
the normal update mechanism.

The save command
saves all header information on the save tape, and the restore command automatically restores this information. However, the t-dump and t-load commands do not save/restore
the header. Instead, the t-load command generates
new header information as if the items were being updated normally.
