<LTYPE> token is used for declaring a variable which is local
to the subroutine in which it is used, whereas
<TYPE> is used
to declare a variable which is passed to the routine as an argument.
In practice, the translation for both of these tokens is identical
for all types except CHARACTER.
In the CHARACTER type, a variable passed as an argument is declared
CHARACTER*(*), but a local variable is declared CHARACTER*
<CHASIZ> is replaced by the ``local character size.''
If not told otherwise, GENERIC will replace
<CHASIZ> by 200,
making local character variables CHARACTER*200.
It is possible to override this default character size
if it is unsuitable. You can define the environment4 variable
GENERIC_CHASIZ or you can use the -c flag on the
