Variables

 
 
 
 VARIABLES
 
Variables as used in Control Basic consist of conventional variables, and points.
 
LOCAL VARIABLES
 
There are 26 local variables available to each program. These variables can assume any floating point value. The current value of a local variable can be determined by using the PRINT command (i.e.: PRINT A). Local variables  are unique to each program and cannot be used anywhere else in the system. The symbols used for local variables are the characters of the alphabet (i.e.: A,B,C...Z).
 
POINTS
 
The 10 point types are variables because they have a value. This value may be accessed, and some points are set through Control Basic. The table below summarizes the fields of each point that can be read or written to:
POINT TYPE
MNEMONIC
READ FIELD
WRITE FIELD

All point type variables  can be referred to by their label. Some statements and functions would be illogical using certain points. If an illogical operation is attempted, nothing will happen.
 
Examples:     START WR1 (cannot start Weekly Routines in BASIC)
 
DMON1 = 23 * A. (DMONS cannot be set by BASIC)
