System Command EDIT

The )EDIT command is used to edit an APL function. There are two forms:

)EDIT

and

)EDIT function

where function is the name of the function to edit. If the function exists, an edit window will be opened and the function will be shown in the window. If the function does not exist, a new edit window will open with an empty function other than the function name on line 0.

Function names, like variables, are case sensitive. PI, Pi, pI, and pi are four different identifiers.

If )EDIT is used with no function name specified, a new edit window will open and a blank line 0 will be presented. The function can be typed in to this window on this line (without using the prefix del (∇) symbol.)

The )EDIT command is treated exactly as the ∇ symbol, a ∇ used alone opens a blank window to edit a new function, ∇ followed by the name of a function opens a window containing the existing function for editing, or opens a new window to define the contents of the function.
