 2 02/14/79: Known bugs in the installed (>unb>bound_fortran_) old_fortran compiler.
 3 
 4 This compiler is the MR6.1/MR7.0 Multics Old Fortran Compiler (old_fortran).
 5 
 6 174  optimizer has reference count problems with parameter
 7       complex arrays
 8 173  statement label symbol table cannot be used by the
 9       system debuggers
10 168  the compiler allows array names in certain contexts
11       that are prohibited by the language.
12 157  an incorrect descriptor packed bit is generated for a
13       complex function return value if the function name is a
14       parameter of the subprogram being compiled and the name
15       does not appear in an external statement.
16 133  Mode statements of the form:
17                     mode*k h_name ...
18       where "h_name" is any name starting with a lower case
19       "h", will not compile correctly. This is due to the
20       compiler interpreting decimal integer followed by "h"
21       as a hollerith constant.

24 Suggested Improvements:
25 144  The following improper sequence is not diagnosed:
26                     do 10 i = 1, 10
27                     if (...) go to 10
28                     do 10 j = 1, 10
29 143  Type conversion of constants is sometimes delayed until
30       execution, resulting is less efficient code. For
31       example:
32                     do 100 x = 0, 13.
33       If x is a real variable, the constant 0 is converted to
34       floating point (0.0) every time the statement is
35       executed.
36 142  Mode statements of the form:
37                     mode*k
38       are emitted by the compiler when using the -convert
39       option, although they are not acceptable to the
40       compiler without this option.

48      old_fortran.bugs.info has a name that follows an earlier convention for
49      info segments containing lists of bug descriptions.  Current info seg
50      guidelines specify a better name:
51         old_fortran.errors.info However, the info segment describes the
52      old_fortran compiler, which is no longer installed in the Multics
53      Libraries.  Therefore, the info will be saved for posterity as:
