Member name conventions

Members created through ISPF must follow this naming convention:

The first character must be alphabetic or special (@ # $)
Characters 2-8 must be alphabetic, numeric, or special (@ # $)

Special characters are as defined in the U.S. English code page (037):

@ (X'7C'), # (X'7B'), $ (X'5B')

All member names created within ISPF are converted to uppercase. If you create members outside of ISPF that do not meet these conventions, they are displayed in ISPF member lists and can be selected from those lists. These member names can also be specified for the Browse service with the exception of member names containing lowercase alphabetics. (ISPF converts the member name to uppercase before searching for the member and therefore cannot process a lowercase member.) Member names not meeting the ISPF naming convention are not supported for the other ISPF services.

Note: ISPF does not support using option M (member list) from a data set list and then selecting E to edit a member whose name contains lowercase letters. ISPF uses the Edit service in this case, and its services do not support lowercase member names.
