 3 This info segment provides temporary documentation for new features of
 4 the  MR12.2 FORTRAN compiler which may not have been documented in the
 5 manual yet.

10    Character variables can now be up to 128K-1 characters long.
11    Character constants can be up to 512 characters long.

14 Character variables:
15 
16 The maximum length of Fortran character variables has been increased
17 to 131071 (128K-1) for MR12.2. Prior to this it was 512. Constructs
18 like the following are now allowed:
19 
20       character a*128000
21 
22 However, character constants (strings) are still limited to 512
23 characters long.
24 
25 When using many large character variables, the compiler may issue the
26 message:
27 
28  FATAL ERROR 414:
29  Implementation restriction: with the relocation of <Variable> in main_
30  the stack frame has overflowed its limit of 62000 words.
31 
32 This can be eliminated by compiling with the -large_array,-la option.

35 Character Constants:
36 
37  Character constants (strings) may now be up to 512 characters long.
38 Previously, they were limited to 256 characters.
