Beware of the symput/symget functions. They deal with macro-vars but the
parameters are string-data-variables, so they _are_ limited to 200 chars.
The memory allocated for _all_ macro-vars is set in an option als well as
the maximum length of macro-vars, which are stored in this memory. The max.
length of macro-vars is 32kByte (in SAS V6). If there are  to many
macro-vars or if they are to big, they are not stored in the reserved
memory-part, they are swaped out (to WORK?).
