NULL STRING FOR CHAR VALUE
You can’t assign null values to control characters with a DEFINE
command.
"OFF" MUST CORRESPOND TO "ON"
If you enter a CENTER OFF, CHANGES OFF, KEEP OFF, or SET BOX OFF
command, you must have previously entered a matching ON command.
Otherwise, TFORM issues this error message.
PAGE NUMBER EXCEEDED LIMIT ON THIS PAGE, RESET TO 1
With its page counter, TFORM automatically keeps track of the number of
pages your file produces as it is processed, regardless of whether the
numbering feature is turned on or off with the PAGE command. When the
page count reaches the page limit of 32500 pages, TFORM resets the page
counter to 1 and starts over to keep the value within bounds.
PAGE NUMBER PARAMETERS RESET TO DEFAULTS
If the page number counter is at too small or too large a number, it is reset
to its defaults.
PARAMETER VALUE ILLEGAL
A parameter value entered in a function reference is unacceptable (for
example, a null string for the ORD function, zero or a negative number for
the ROMAN function, or a character other than L, R, or C for the third
argument of the JUSTIFY function).
