Changing variables for names

z/OS TSO/E Customization
SA32-0976-00

The variables for changing the Information Center Facilitynames function are located in the non-display panel ICQSIECA. Table 1 shows the variables you can change and their default values.

Table 1. Variables for names
Variable Contents Default value
QCANTXT The name of the user's nickname data set.

The TRANSMIT and RECEIVE commands search this data set for nicknames. The names function adds :ALTCTL. tags for the other nickname data sets to this data set so that TRANSMIT and RECEIVE search the other data sets, if needed. If you change the USRCTL parameter of the Interactive Data Transmission Facility, you must change the value of the QCANTXT variable. The USRCTL parameter changes the name of the user's nickname data set.

Note: The name you supply for QCANTXT must not be a fully-qualified data set name. The names function automatically prefixes the user ID to the name of the data set.
NAMES.TEXT
QCAPNTXT The name of the nickname data set for the private directory.
Note: The name you supply for QCAPNTXT must not be a fully-qualified data set name. The names function automatically prefixes the user ID to the name of the data set.
