17	! *
18	! *
19	! A program to convert FORTRAN 77 source form to Fortran 90 source *
20	! form. It also formats the code by indenting the bodies of DO-loops *
21	! and IF-blocks by ISHIFT columns. Statement keywords are *
22	! followed if necessary by a blank, and blanks within tokens are *
23	! are suppressed; this handling of blanks is optional. *
24	! If a CONTINUE statement terminates a single DO loop, it is *
25	! replaced by END DO. *
26	! Procedure END statements have the procedure name added, if *
27	! blanks are handled. *
28	! Statements like INTEGER2 are converted to INTEGER(2), if blanks
29	! are handled. Depending on the target processor, a further global *
30	! edit might be required (e.g. where 2 bytes correspond to KIND=1). *
31	! Typed functions and assumed-length character specifications are *
32	! treated similarly. The length specification 4 is removed for all
33	! data types except CHARACTER, as is 8 for COMPLEX. This
34	! treatment of non-standard type declarations includes any *
35	! non-standard IMPLICIT statements. *
36	! Optionally, interface blocks only may be produced; this requires *
37	! blanks processing to be requested. The interface blocks are *
38	! compatible with both the old and new source forms. *
39	! *
40	! Usage: the program reads one data record in free format from the *
41	! default input unit. This contains: *
42	! *
43	! name of file *
44	! indentation depth *
45	! maximum indentation level *
46	! whether significant blanks should be handled *
47	! whether interface blocks only are required *
48	! *
49	! The default values in the absence of this record are: *
50	! name 3 10 T F *
51	! To do nothing but change the source form of a file prog.f type *
52	! prog 0 0 F F *
53	! or simply *
54	! prog / *
55	! For more extensive processing type, say, *
56	! prog 3 10 t f *
57	! and for interface blocks only type *
58	! prog 0 0 t t *
59	! The input is read from prog.f, the output is written to prog.f90; *
60	! there should be no tabs in the input. *
61	! *
62	! Restrictions: The program does not indent FORMAT statements or *
63	! any statement containing a character string with an *
64	! embedded multiple blank. *
65	! The order of comment lines and Fortran statements *
66	! is slightly modified if there are sequences of *
67	! more than KKLIM (=200) comment lines. *
68	! If there are syntax errors, continued lines do not *
69	! have a trailing &. *
70	! When producing interface blocks, a check is required*
71	! that any dummy argument that is a procedure has a *
72	! corresponding EXTERNAL statement. Also, since no *
73	! COMMON blocks or PARAMETER statements are copied, *
74	! part of an assumed-size array declaration may be *
75	! missing. Similarly, parts of an assumed-length *
76	! character symbolic constant might be copied and have *
77	! to be deleted. BLOCK DATA statements are copied and *
78	! must be deleted. These problems would normally be *
79	! detected by a compiler and are trivially corrected. *
80	! Within a given keyword, the case must be all upper *
81	! or all lower, and lower case programs require *
82	! blank handling for correct indenting. *
