NAME
       getenv - get value of environment variables

SYNOPSIS
       subroutine getenv (ename, evalue)
       character*(*) ename, evalue

DESCRIPTION
       The  getenv  subroutine	searches the environment list (see environ(5))
       for a string of the form ename=value and returns	 value	in  evalue  if
       such a string is present; otherwise, it fills evalue with blanks.

       If evalue is too short to hold the complete string value, the string is
       truncated to fit in evalue.
