At the moment, the following sections describe only those language features that are New or Enhanced relative to the Extended APL Standard, or that deserve special comment.

Syntax

Primitive functions

Primitive operators

Datatypes

System Commands

System Commands provide features to the user of the APL system, separate from actual workspaces, variables or APL operators. These provide such features as accessing files, saving a workspace, and exiting the APL interpreter. The commands are not case sensitive, so )IN and )in do the same thing.

NARS2000 currently has the following system commands:

)BOX Turn ON/OFF box around output
)CLEAR Start a new session manager window with an empty workspace
)CLOSE
)COPY
)DROP
)EDIT Create a new function in the workspace or edit an existing function
)ERASE Delete a variable or function in the current workspace
)EXIT Close down the interpreter and exit the program. Same as )OFF
)FNS
)FOP Display functions, operators, and hyperators. Same as )FOPS
)FOPS
)HYP Display hyperators only
)IN
)INASCII    
)LIB
)LAOD Alternative spelling of )LOAD
)LOAD Load an existing workspace
)NEWTAB
)NMS
)OFF Close down the interpreter and exit the program. Same as )EXIT
)OPEN
)OPS Display operators only
)OUT
)RESET
)SAVE Save the current workspace
)SVAE Alternative spelling for )SAVE
)SI workspace State Indicator
)SIC State Indicator Clear
)SINL
