Introduction

The characters used by this wiki and by NARS2000 when writing a workspace to disk have a specific name in order that they can be displayed in ASCII text and if necessary for display purposes they have a specific Unicode value so that they can be read exactly if read from a binary file and so they can be displayed within the APL font.

When it is necessary to describe a character it's usually easier to remember the name than a hexidecimal code number. For example, the APL quad symbol "⎕" is internalized as Unicode U+9109 (or hex 2385), it can be displayed on a web page using the symbol ⎕ (or &#x2385) or can be referenced on this wiki by the name {quad}. This wiki is set up to show these brace symbols as APL characters in ordinary text.

If you want to show a series of apl characters in monospace, you can surround them block like this: <apl>{quad}</apl> (which looks like this: ) for regular size APL characters (which may be cut off on some displays), or <apll>{quad}</apll> for larger APL characters also in a monospace font, and looks like this: .

Names

The following are the names for the APL symbols. Some symbols have more than one name; either the typical APL use name is used or the description if there isn't a standard function name. If there is more information about the symbol the name will be a link; click on the link to go to the page for how the symbol is used. If a column has up/down arrows next to the name, you can re-sort the table on that column, either ascending or descending.

Notes

[1] NARS2000 generates the underlined characters using the Unicode Private Character range 57398-57423 or 0xE036-0xE04F; the SimPL Medium and APL385 Unicode fonts can use the circled letters at 9398-2423 or 0x24B6-0x24CF to substitute for these.

[2] The ABS/MAGNITUDE/MOD/RESIDUE symbol is typed as character 124, but the Unicode symbol is 2223.
