Chapter 5. System Variables and System Functions
SYSTEM VARIABLES
System variables provide controls for the system and information about the sys-
tem to the user. These variables can be used by a function as arguments the same
as any variable.
The following
is a list of the system variables and their meanings. A complete des-
cription
of each follows the list:
Variable Name Meaning
OCT
Comparison
tolerance
010
Index origin
OPP
Printing precision
OPW
Printing width
ORL
Random link
OLC
Line
counter
OWA
Workspace available
OLX
Latent expression
OAV
Atomic vector
Notes:
1. To find the value assigned to a system variable, enter the variable name. The
value assigned to the OCT, 010, OPP, OPW, ORL, and OLX system variables
can be changed by using
the assignment arrow (~). For example, entering
010+-0 assigns the value 0 to the 010 system variable.
2.
The use of any system variable causes an entry to be made in the symbol table
for that symbol. Therefore, if the symbol table is full, a SYMBOL TABLE FULL
error is generated.
