NAME
     incr - Increment the value of a variable

SYNOPSIS
     incr varName ?increment?


DESCRIPTION
     Increments the value stored in 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 in variable varName and also returned as result.
