Subject:      A Problem with sas variables

I have few question:

1)I have a variable which is 120 character long. But I need to change
either the length of the variable or take first 20 character of values
which ever is better. How can I do that? I can not use Length statement
cause the length of this variable is pre determined.

2) For the variable X  I have the following value:

          Pre dose/ base line
           Pre done/ Follow up

I do not need the pre dose porting. My output should be:
          base line
           Follow up
How can I do that.
Thanks for your help
