NAME
    error - generate a value of specified error type

SYNOPSIS
    error([n])

TYPES
    n		integer, 0 <= n <= 32767; defaults to errno()

    return	null value or error value

DESCRIPTION

    If n is zero,  error(n) returns the null value.

    For positive n, error(n) returns a value of error type n.

    error(n) sets calc_errno to n so that until another error-value
    is returned by some function, errno() will return the value n.

EXAMPLE
    ; errmax(errcount()+1)
	   20
    ; a = error(10009)
    ; a
	   Error 10009
    ; strerror(a)
	   "Bad argument for inverse"
