Workspaces are now available. (See "status.doc" to see whether your
J version has workspaces.) The current internal representation follows
WSIS (workspace interchange standard), meaning (a) except for contents
of literal arrays, only ASCII 32-126 occurs in a workspace; and
(b) it MAY be possible to transfer data arrays between J and other
APL systems.

The relevant functions are as follows.  All function ranks are zero.

 x  2!:0  y      WS Name Class
    2!:1  y      WS Name List
[x] 2!:2  y      WS Save
[x] 2!:3  y      WS PSave
[x] 2!:4  y      WS Copy
[x] 2!:5  y      WS PCopy
 x  2!:55 y      WS Erase

B
    5!:3  y      String (WSIS) Representation
