Some functions such as LEFT, TRIM, and COMPRESS have a default length
based on their first parameter.  These functions are used in
concatenations (||).  The compiler temporary variables used to store
intermediate results of a concatenation will be 32K, and they will not
be freed for other operations to use.  As a result, these concatenations
will use excess memory and may produce these messages in the SAS Log:

   ERROR: Out of memory.
   FATAL: Error occurred in the code generation subsystem during program
          load.

Performance degradation may also be encountered, without the error
message above.

To circumvent the out of memory problem, either increase the memory
allocation or reduce the number of concatenations in the code.  To
alleviate performance degradation, reduce the code dependency on
functions that have a default length based on their first parameter.

This has been fixed in SAS 9.1.
