- - Improved documentation.
-
- May 1991
- - Bugs fixed (thanks to Edgar SouliƩ for finding these): In some
- situations // was generated instead of **. Equals signs in FORMAT or
- PARAMETER statements caused errors. Generate continuation lines on long
- warning messages.
- - Accept lower-case keywords. Previously IF and the C for comments had to
- be in upper-case.
- - Improved TAN derivative. Continuation character in variable list in
- STSC version. Slightly more memory available under I-APL (by using
- direct definitions).
- - GRAD.DOC corrections/additions: Document restriction on re-assigning the
- independent variables (in (a)). Use of lower-case in function and
- variable names (see (f) and (h)). Comments on Fortran 66 vs Fortran 77
- and on case sensitivity dropped (GRAD now well tested with F77). Warn
- about possible name clashes when choosing the delimiter, and about
- dimensioning any new arrays. Drop suggestion on fixing assignment
- labels (worked for GO TO but not for DO loop labels).
- - CHANGES.DOC added.
