The Session Manager is similar to the one in APL+Win (which was modeled after an old product of mine, TallScreen).

Features

  • The cursor may move about the screen changing text as desired. If you press Enter on a line, the original text of that line is restored, the changed line is copied to a new line at the bottom of the screen buffer and executed.
  • Text may be selected with the mouse and copied using Ctrl-C or Copy from the Context (right-click) or Edit menus.
  • Text may be pasted into the Session Manager from various formats. If the source text is all Unicode, Ctrl-V or Paste from the Context or Edit menus may be used. If the source text includes APL characters in a format different from Unicode, try one of the options in the Paste APL choice from the Context or Edit menus. Text coming from the ISO Extended APL Standard, APL+Win, APL2, and PC/3270 is supported. If you know of other systems that use a character mapping not covered by these choices, please let us know by sending a message on one of the forums.
  • Multiple workspaces may be open at the same time by used of tabs along the top of the Session Manager window. Click on a tab to bring the corresponding workspace to the forefront.
  • Workspaces are saved as plain text ASCII files with an extension of .ws.nars.
  • To invoke the function editor, type ∇ by itself, or ∇ followed by a name, or )EDIT by itself, or )EDIT followed by a name, or double-right-click on a function name in the session manager or function editor windows.
  • The function editor supports a multilevel Undo. That is, pressing Ctrl-Z reverts back to the previous text.
  • Each function's undo buffer is saved with the function for reuse the next time that function is edited.
  • All function's undo buffers are saved with the workspace for reuse on the next load.
  • The text entered in both the Session Manager and Function Editor is colored according to its syntaxual contents.

APL Font

As NARS2000 is a Unicode-based program, you'll need an attractive Unicode APL font to display all the characters. To that end, I've made an arrangement with Phil Chastney to bundle a version of his APL Unicode font SImPL called SImPL medium. From the NARS2000.zip file, extract the SImPL-Medium.ttf file to your Windows fonts directory. Note that this font is licensed for distribution with NARS2000 only. See the Other APL Unicode fonts likely will work well as long as they contain all of the characters we use such as infinity (∞), zilde (⍬), circle-middle-dot (⊙), dieresis-jot (⍤), dieresis-tilde (⍨), etc. Also, in order to display the circled numbers on the left of each workspace tab, you'll need a font like Code2000 which you can download from the 'net.

Keyboard Mapping

The mapping of APL characters to the keyboard is similar to that of APL+Win, although other keyboard mappings may be supported in the future. To see a graphic display of the current keyboard, take a look at the NARS2000 Keyboard.
