When using REX external to Metamorph in Windows or Unix, it can
occasionally occur that a very complicated expression requires more
memory than is available. In the event of an error message indicating
not enough memory, you can try the same expression using
"REXL", another version of REX compiled for large
model. As "REXL" is slightly slower than "REX" it
would not be recommended for use in most circumstances.
The beginning of line (^) and end of line ($)
notation expressions for Windows are both identified as a 2 character
notation; i.e., REX under Windows matches \X0d\X0a (carriage
return [cr], line feed [lf]) as beginning and end of
line, rather than \X0a as beginning, and \X0d as end.
