L6 USER—L6 First Request
L6 USER—L6 First Request
This trace record is generated immediately after the first of a series of data requests
(Request Code -00003) or typed data requests (Request Code -00005) is
received from the APS user. A series of such records consists of:
L6 First Request
L6 Multi Mid Request (zero or many)
L6 Multi Last Request or L6 Multi Abort Request
No other L6 Requests can be handled until the series is complete or aborted.
This example shows concatenated tokens which would not be present with a typed data
request. It also shows a single user data element. Note that the number of data elements
depends on the user application.
APS decides how to segment the user's original data so that the request always contains
a whole number of user data elements. This means that the user data elements structure
of this request may be different from the structure submitted by the user.
Subtype

SU Name

Request Addr

Request code
is either:
02/06/91 12:17:14.065654 >000.273334 #153 TAPS L6 USER
L6 First Request Su Name #ZMF000B
