ZAPS-VAL-CNTXT-RSN-xxx is the reason code for elements of the presentation
context definition result list. This value applies only to presentation and ACSE
connections. For further information on the use of these values, see ZAPS-DDL-PRES-
CNTXT-RLIST earlier in this appendix.
CONSTANT ZAPS-VAL-CNTXT-RSN-NOVALUE VALUE 0.
CONSTANT ZAPS-VAL-CNTXT-RSN-NORSN VALUE 1.
CONSTANT ZAPS-VAL-CNTXT-RSN-NOABS VALUE 2.
CONSTANT ZAPS-VAL-CNTXT-RSN-NOTRANS VALUE 3.
CONSTANT ZAPS-VAL-CNTXT-RSN-DCSLIMIT VALUE 4.
ZAPS-VAL-CNTXT-RSN-NOVALUE shows that no value has been given.
ZAPS-VAL-CNTXT-RSN-NORSN shows that no reason is specified.
ZAPS-VAL-CNTXT-RSN-NOABS shows that the abstract syntax is not supported.
ZAPS-VAL-CNTXT-RSN-NOTRANS shows that the proposed transfer syntaxes are
not supported.
ZAPS-VAL-CNTXT-RSN-DCSLIMIT shows that the local limit on the defined context
set (DCS) is exceeded.
ZAPS-VAL-CON-xxx shows the response, by the called user application and/or the
service provider, to a connection attempt. Note that you receive only those values
reported by the service layer you are using.
When you use the APS_ASSOC_CONNECTRSP_ procedure, you are the called user.
In this case, you must either give the ZAPS-VAL-CON-ACCEPT value to accept the
connection, or give one of the ZAPS-VAL-CON-U-xxx or ZAPS-VAL-CON-REJECT-
xxx values that follow to reject the connection. In the latter case, you must specify a
value that applies to the OSI layer you are using.
By calling APS_ASSOC_GETPARAM_ , you can retrieve the connect result sent by the
remote application and/or the service provider.
