From the CA-7 System Programmer Guide manual:
Mixed Case Support in CA-7 Editor
Character translation controls can be set in the CA-7 Editor. New Editor subcom-
mands 'UPPER' and 'MIXED' determine whether editor data is translated to uppercase
or left "as is."
These subcommands are enabled with a new initialization file option. If this option
is not coded, then all edit data is translated to uppercase.
So whether or not you can use the lower-case letter in your PARM will depend upon how your site set up the initialization parameters when CA-7 was installed. Hence, you need to consult with your site support group (and whoever installed CA-7 in particular) to answer your question.
