Hello,

The record reference manual says a record name is "An arbitrary 28 character record name supplied by the application developer" but we know that the " ", ".", and "&" characters don't work...what is the allowed character set for EPICS record names, or alternatively, the set of disallowed reserved characters?
We are trying to interface another system (i.e. with different data naming conventions) with epics/channel access.

many thanks,

Judy, et al

Here's the relevant section from the Application Developer's Guide:
6.3.2 Unquoted Strings

In the summary section, some values are shown as quoted strings and some
unquoted. The actual rule is that any string

consisting of only the following characters does not have to be quoted:

a-z A-Z 0-9 _ - : . [ ] < > ;

These are also the legal characters for process variable names. Thus in many
cases quotes are not needed.
