A-: 40
523 MESSAGE INTEGER CONSTANT IS REQUIRED - OPTION IGNORED (523)
W CAUSE This compiler option requires an integer parameter; such as
WIDTH. The compiler has ignored this option.
ACTION Check the syntax and insert an integer where necessary.
---------------------------------------------------------------------------------------
524 MESSAGE SUBPROGRAM "! " SPECIFIED, BUT NOT FOUND (524)
W CAUSE A procedure or function name specified in the SUBPROGRAM option
was not found in the source.
ACTION Check the spelling of the procedure or function.
---------------------------------------------------------------------------------------
525 MESSAGE ANY EXTERNAL GOTO TO THIS LABEL IS AN ERROR (525)
W CAUSE This label marks a component statement of a structured
statement. This label cannot be referenced by a GOTO statement
contained in an external procedure or function, but that error
will not be detected until the program is prepared or executed.
ACTION Make sure no nonlocal GOTOs branch to this label.
---------------------------------------------------------------------------------------
526 MESSAGE EXPRESSION FOLDED TO THE EMPTY SET (526)
W CAUSE The compiler has determined that a set expression results in an
empty set and folded that expression to empty. This warning
appears in case the user expected side effects or made some
kind of error that caused the folding. Folding occurs when an
intersection is performed with the empty set, the empty set
occurs on the left side of the set difference operator, or two
empty sets appear in a set operation.
ACTION Check to see if expression should fold to the empty set.
---------------------------------------------------------------------------------------
527 MESSAGE 'ON' OR 'OFF' IS REQUIRED HERE (527)
W CAUSE The word ON or OFF is required after this compiler option name;
for example, $LIST$.
ACTION Correct the option argument and the compiler option syntax.

528 MESSAGE PREVIOUS VERSION OF '!' INACTIVATED (528)
W CAUSE A procedure or function by the same name already exists in the
USL file and has been inactivated.
CAUSE If PRIVATE_PROC was ON, then two level 1 procedure or function
names are not unique within the first 15 characters, or a copy
from a previous compilation is being replaced.
CAUSE If PRIVATE_PROC was OFF, then either duplicate non-level 1
procedure or function names exist (they are not unique within
15 characters) or duplicate procedure or function names have
been introduced due to separate compilation of procedures or
