• Fix SourceForge bug #450465 (`create columns from function' was broken).

13.1.5: Version 2.8.0 [2001 Jul 30]

• Add `unlink' command as a unix-familiar way to delete files (see Unlink).
• Add `set page size' command to clip to a given page size (see Set Page).
• Add `substr' RPN operator to permit extraction of sub-strings (see Tertiary Operators).
• Add `default' possibility for the `set x name' and the `set y name' commands.
• Add Perl-like ability to put underscores in numerical constants, to guide your eye. These underscores are ignored by Gri, so that for example `.v. = 1_000' and `.v. = 1000' are equivalent as far as Gri is concerned.

Emacs mode (see Emacs Mode)

• Give `M-Tab' the ability to complete builtin variables and synonyms as well as commands
• Add ``idle-timer minibuffer help'' to display defaults for builtin variables under the cursor.
• Add fontification of builtin variables only if they are spelled correctly.

Developer changes

• Add `make source-arch-indep' target in sources. This will build a source tar file in which all the architecture-independent material (documentation in HTML, postscript and Info formats) is pre-made. This makes it easier to install gri on a host that doesn't have TeX and ImageMagick installed.
• Complete the port to IBM's compiler for their AIX operating system.
