YOU ATTEMPTED AN INFINITE SERIES OF SUBSTITUTIONS
A recursive assignment would have continued indefinitely if TFORM
hadn’t caught it and reported it with this message. An example of such is:
\ASSIGN is_a_rose "\\(is_a_rose\\)"
Gertrude says, "Rose \(is_a_rose\)."
YOU HAVE REACHED THE LIMIT FOR NUMBER OF OPEN FILES
Only four auxiliary files can be open at any given time. If you have opened
four files with the FILE READ command, TFORM will return this error
message. The same is true if you have opened four files with the FILE
WRITE command.
YOU MAY NOT SPECIFY "VERBATIM" FOR TTEXT FILES
The VERBATIM keyword cannot be used when a T-TEXT file is sourced in
with the SOURCE command; TFORM needs to be able to read the profile of
the T-TEXT file.
