Description The AND operator performs the logical AND function on the corresponding
bits of the integer parts of two valid BASIC expressions.
The logical AND function between two bits is defined as follows:
0 AND 0 = 0
0 AND 1 = 0
1 AND 0 = 0
1 AND 1 = 1
Arguments • expression1
Any valid BASIC expression.
• expression2
Any valid BASIC expression.
Example VR(0) = 10 AND (2.1*9)
The parentheses are evaluated first, but only the integer part of the result, 18,
is used for the AND operation. Therefore, this expression is equivalent to the
following:
VR(0) = 10 AND 18
The AND is a bit operator and so the binary action is as follows:
01010 AND 10010 = 00010
Therefore, VR(0) will contain the value 2.
Example IF MPOS AXIS(0) > 0 AND MPOS AXIS(1) > 0 THEN GOTO cycle1

Type System parameter
Syntax AOUT(analogue_chan)
Description This command sets the output value of the +/-10V analogue output channels
that are provided by connecting JEPMC-AN2910 modules on the MECHA-
TROLINK-II bus. The range of the value set is [-32000, 32000] for voltage
range [-10V, 10V].
Arguments • analogue_chan.
Analogue output channel number 0.31
Example No example.

Type Mathematical function
Syntax ASIN(expression)
Description The ASIN function returns the arc-sine of the argument. The argument must
have a value between -1 and 1. The result in radians is between -PI/2 and PI/
2. Input values outside this range return 0.
Arguments • expression
Any valid BASIC expression.
Example >> PRINT ASIN(-1)
-1.5708

Type Mathematical function
Syntax ATAN(expression)
Description The ATAN function returns the arc-tangent of the argument. expression can
have any value. The result is in radians and is between -PI/2 and PI/2.
Arguments • expression
Any valid BASIC expression.
Example >> PRINT ATAN(1)
0.7854
