IBM 5100 Apl Reference Manual

12
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.
The system command can be entered one character at a time from the
keyboard.
2. The system commands )LOAD, )SAVE, )CONT, )US, )FNS, )VARS, )COPY,
)WSID,
)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:
• 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
Tape 1, file 1
02
Tape 1, file 2
2002
Tape 2, file 2
