NAME
    SetVar -- Sets a local or environment variable (V36)

SYNOPSIS
    success = SetVar( name, buffer, size, flags )
    D0                 D1     D2     D3    D4

    BOOL SetVar(STRPTR, STRPTR, LONG, ULONG )

FUNCTION
    Sets a local or environment variable.  It is advised to only use
    ASCII strings inside variables, but not required.

INPUTS
    name   - pointer to an variable name.  Note variable names follow
             filesystem syntax and semantics.
    buffer - a user allocated area which contains a string that is the
             value to be associated with this variable.
    size   - length of the buffer region in bytes.  -1 means buffer
             contains a null-terminated string.
    flags  - combination of type of var to set (low 8 bits), and
             flags to control the behavior of this routine.  Currently
             defined flags include:

            GVF_LOCAL_ONLY - set a local (to your process) variable.
            GVF_GLOBAL_ONLY - set a global environment variable.

            The default is to set a local environment variable.

RESULT
    success - If non-zero, the variable was sucessfully set, FALSE
              indicates failure.

BUGS
    LV_VAR is the only type that can be global
