You can change the naming convention by modifying the ISTDEFIN command list. A set of directions is provided in the ISTDEFIN command list for supplying a seed value to control the values for the first two characters of the device name. For example, if you want to have your device names begin with MY, change the following in the ISTDEFIN command list:

seed='MY'                 /* user seed value */

Thus, the name generated for the definition of a device at X'123' is named MY0123D.
