@(1CSH)                 COMMAND REFERENCE                 @(1CSH)



NAME
     @ - shell variable assignment (csh built-in)

SYNOPSIS
     @ [ variable_operation ]

DESCRIPTION
     With no arguments, @ prints the names and values of all
     shell variables.  With arguments, the assignment is done.

     The normal form for variable_operation is variable = expr.
     The variable argument may either be a variable name or a
     reference to a member of a vector variable (the variable and
     element referenced must already exist).  The expr argument
     is a numerical expression involving integers.  See csh(1csh)
     for a complete description of expressions.  In addition,
     operators such as *=, +=, and so forth, are available as in
     C.  The spaces around the `=' are optional.

     An alternate form of variable_operation involves the ++
     (increment) and -- (decrement) operators.  For example, the
     command ``@ i++'' increments the value of the variable i.

EXAMPLES
     The following shell script prints the integers from 1 to
     100.

          #!/bin/csh -f
          set a=1
          while ($a <= 100)
               echo $a
               @ a++
          end

RETURN VALUE
     [NO_ERRS]      Command completed without error.

     [1]            An error of the type described in the message
                    occurred.

CAVEATS
     Spaces are required in separating elements of the
     expressions.
