Create monadic System Function Quad EX (EXpunge object)

New page

⎕EX function available in monadic form.
==Monadic Function==
{{BoxStart|<apll>Z←⎕EX R</apll>
|expunges or deletes the named object from the APL workspace, similar to )ERASE command. <apll>R</apll> should be a character string of the function or variable name to delete.}}
{{BoxLine|<apll>R</apll> is a character scalar or vector (function or variable '''name''' string).}}
{{BoxEnd|<apll>Z</apll> is a scalar number, usually 1. '''1''' means '''success''', object was '''deleted'''. 0 means failed, object not deleted.}}

Monadic function ⎕EX behaves much the same as described in the Extended APL Standard.

The following deletes variable '''X''' from the workspace:

<apll>       X←45 99 
       ⎕EX 'X' 
1 
</apll>
One important difference between '''⎕EX''' and ''')ERASE''' is: '''⎕EX''' can be used inside a ''user function''.
