All system commands (and only system commands) have as their first character
a right parenthesis. Each system command must begin on a new line. Para-
meters (required or optional information) for the system commands must be
separated by blanks. System commands cannot be used within APL instructions
and cannot be used as part of a function definition (function definition is dis-
cussed in Chapter 6).
System commands can be entered two ways:
1.
2.
The system command can be entered one character at a time from the
key board .
The system commands )LOAD, )SAVE, ICONT, )LIB, IFNS, )VARS, )COPY,
IWSID, )OUTSEL and )REWIND can be entered in one operation by holding
the CMD key while pressing the top-row key just below the label of the
command you want.
The parameters, if required, must be entered and the EXECUTE key pressed before
any operation will take place. Following is an explanation of terms and symbols
used as parameters for system commands:
0 Device/file number specifies the tape unit and file to be used. The built-in tape
unit is tape unit 1 and the auxiliary tape unit is tape unit 2. If the value speci-
fied is less than four digits, tape unit 1 is assumed and the value specified re-
presents only the file number. If the value specified is four digits, the right-
most three digits specify the file number and the leftmost digit specifies the
tape unit. For example:
Device/File Number Meaning
1 Tape 1, file 1
02 Tape 1, file 2
2002 Tape 2, file 2
0 Workspace ID is any combination of up to 11 alphabetic or numeric characters
(with no blanks); however, the first character must be alphabetic. If more than
11 characters are entered, only the first 11 are used.
0 Password is any combination of up to eight alphabetic or numeric characters
(with no blanks). If more than eight characters are entered, only the first
eight are used.
O&t is a user-defined function or variable name.
