       append - Append to variable

1mSYNOPSIS0m
       1mappend 4m22mvarName24m ?4mvalue24m 4mvalue24m 4mvalue24m 4m...24m?


1mDESCRIPTION0m
       Append all of the 4mvalue24m arguments to the current value of variable 4mvar-0m
       4mName24m.  If 4mvarName24m doesn't exist, it is given a value equal to the  con-
       catenation  of all the 4mvalue24m arguments.  This command provides an effi-
       cient way to build  up  long  variables  incrementally.   For  example,
       ``1mappend  a  $b22m''  is  much more efficient than ``1mset a $a$b22m'' if 1m$a 22mis
       long.
