The user can change certain parameters of the APL system via ŚCONF. The extent to which ŚCONF is implemented varies from system to system. The current range of options is:
5 ŚCONF 0 = disable interrupts, 1 = enable interrupts 6 ŚCONF (date format) (time format) (display order) date 0 = US 8 character mm/dd/yy 1 = US 10 character mm/dd/yyyy 2 = European 8 character dd/mm/yy 3 = European 10 character dd/mm/yyyy 4 = ISO yyyy-mm-dd time 0 = 24 hour US hh.mm.ss 1 = 24 hour European hh:mm:ss 2 = 12 hour US hh.mm.ss am 3 = 12 hour European hh:mm:ss am order 0 = time before date 1 = date before time 7 ŚCONF Preferred workspace size for this workspace (in bytes), or 0 for the default value, -1 for 'as much as possible' 8 ŚCONF APL component file-system name, as a character vector
In each case the result returned by ŚCONF is the previous value.
The Interrupt Checking Flag is a workspace parameter. A workspace can be saved with attention checking off, thereby preventing the latent expression being interrupted. )CLEAR will enable interrupts.
The Date/Time Format controls the display format adopted by )TIME )SAVE )LOAD and the ’ editor.
The Preferred Workspace Size parameter applies to the current workspace if you )SAVE it, and then it is loaded by double-clicking on the workspace icon or by dragging the workspace on to the APLX program icon. When APLX starts up, it will be allocated the workspace size if possible. This value does not affect the workspace size if you )LOAD the workspace once APLX is already running.
The APL Component File-System Name is the filename used for component-file operations using the Ô Ő Ň Ó primitives. It defaults to 'aplsfile.afl'. If you change the name using 8 ŚCONF, the change applies only for the current APL session; when you restart APLX, the name reverts to the name stored in the APLX preferences file.
