TFORMCVT: Converting From TGAL to TFORM

Diagnostic Messages
If TFORMCVT encounters a command that can’t be translated to TFORM,
or that is positioned wrongly for TFORM’s requirements, or that may have
an unforeseen effect, it inserts one or more comments in the output file at
the point where the command appears. At the end of the file, it attaches
comments that tell how many such warnings were issued and where the
last one occurred; that warning in turn indicates where the previous one
occurred, and so on to the first error in the file.
Untranslatable Commands If a valid TGAL command has no TFORM equivalent, TFORMCVT
converts the input TGAL command into a comment and flags the
command with a warning message that lists the edit input line number. If
there were any previous warning messages, TFORMCVT adds another
comment that shows the line number where the last error message
occurred. For example, if LINENO ON occurred on line 133.3 and the
previous warning message was on line 127, TFORMCVT shows the
following in the output file.
\COMMENT LINENO ON
\COMMENT ^ WARNING **** COMMAND NOT RECOGNIZED. LINE: 133.3
\COMMENT **** LAST WARNING OCCURRED ON LINE: 127
This error message applies to the following four commands.
1. LINENO commands
2. An OUT command containing one or more text strings
3. An OV command that attempts to overprint more than two different
characters other than “_” in a given character position.
4. PAUSE commands
