Echo Commands

On One of machine i am trying to run below echo commands but null output is there any mistake in running these commands.

$ echo $FORMS_RECORD_GROUP_MAX
$ echo $FORMS_CATCHTERM

I have no idea where those variables are coming from ?

maybe try:

printenv FORMS_RECORD_GROUP_MAX

and

printenv FORMS_CATCHTERM

or maybe you need to export the display first (?)
