EPI CHANGE lets you change an existing definition of a virtual terminal. You can only change virtual terminals that are currently in an inactive state.
EPI CHANGE has the following format:
ADDRESS EPI "CHANGE keywords"
{termname|ALL|*}
[PASSWORD(termpswd)]
[APPLID(prodappl)]
[LOGMODE(modename)]
[LOGONPARM('parmstring')]
[ACCEPT|REJECT]
[NORETRY|RETRY(seconds retries)]
Defines the name of the virtual terminal being changed, which must match the name of an APPL statement in your VTAM definition list library.
The CHANGE ALL command can save you time in modifying your virtual terminal definitions. If you define and activate new virtual terminals after you have issued the CHANGE ALL command, reissue the CHANGE ALL command to give your new virtual terminals the same characteristics as the other terminals.
Gives the current virtual terminal the new definition through the SETTERM command.
(Optional) Provides the password for the named virtual terminal, or for all virtual terminals if you are issuing the CHANGE ALL command. Use this keyword only if the VTAM APPL statement for this virtual terminal includes the PRTCT keyword, which allows VTAM to provide password protection. The password that you specify with the CHANGE command must match the password, if any, on the VTAM APPL statement for this virtual terminal.
Alternatively, you can specify the PASSWORD keyword on the EPI ENABLE command.
(Optional) Defines the VTAM application name of the external product that this virtual terminal is logged on to. See the description of the EPI LOGON command. You can either specify the APPLID keyword in the CHANGE command or enter it when you log on to EPI. If you supply a prodappl value at logon and on the CHANGE command, the value that you supplied at logon takes precedence.
(Optional) Defines the name of the entry in the VTAM logmode table to be used when this virtual terminal is logged on. This entry should describe an SLU2 type virtual terminal used by IBM 3278 terminal models 2, 3, or 4.
If neither your CHANGE command or the LOGON command that you issue for this terminal specifies a logmode, EPI uses the default logmode table entry (as defined by VTAM for your system) for this virtual terminal.
(Optional) Defines the character string, enclosed in quotation marks, that EPI passes to an external product when this virtual terminal logs on to that product. Supply a parmstring on your CHANGE command or when you log the virtual terminal on to an external product is optional.
(Optional) These mutually exclusive keywords determine whether EPI accepts requests from external products to acquire this virtual terminal. VTAM does not allow disabled virtual terminals to be acquired.
(Optional) Overrides a previously issued EPI CHANGE or LOGON command for this virtual terminal that specified RETRY. When you specify NORETRY, EPI does not allow retrying of LOGON commands, and does not try to reestablish a session that fails after logon.
(Optional) Overrides a previously issued EPI CHANGE or LOGON command for this virtual terminal that specified NORETRY. The seconds value specifies how many seconds EPI waits between attempts to log on to a virtual terminal or to reestablish a failed session. Use a value from 1 through 86400 (the number of seconds in 24 hours). The default value is 30 seconds. The retries value specifies how many times EPI can try to log on to a virtual terminal or to reestablish a failed session. The default value is 0, which allows only one retry attempt. If that attempt fails, EPI places the virtual terminal in NORETRY mode. You can specify any number of retries up to 65535.
The following sample coding statement changes the logmode value for all virtual terminals to T3278M2:
CHANGE ALL LOGMODE(T3278M2)
