Other REX Notes

  • 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.
