NAME
       incr - Increment the value of a variable

SYNOPSIS
       incr varName ?increment?


DESCRIPTION
       Increments the value stored in(1,8) the variable whose name is varName.  The
       value of the variable must be an integer.   If  increment  is  supplied
       then  its  value  (which  must  be an integer) is added to the value of
       variable varName;  otherwise 1 is added to varName.  The new  value  is
       stored  as  a  decimal  string(3,n) in(1,8) variable varName and also returned as
       result.
