Using Binary Variables
The following examples illustrate the 6000 Series product's ability to perform bitwise
functions with binary variables.
Storing binary values. The 6000 Series Language allows you to store binary numbers
in the binary variables (VARB) command. The binary variables start at the left with the least
significant bit, and increase to the right. For example, to set bit 1, 5, and 7 you would issue
the command VARB1=b1xxx1x1. Notice that the letter b is required. When assigning a
binary value to a binary variable, only the bits specified are affected—all unspecified bits are
left in their current state.
Example Response
VARB1=b1101XX1 *VARB1=1101_XX1X_XXXX_XXXX_XXXX_XXXX_XXXX_XXXX
Storing hexadecimal values. Hexadecimal values can also be stored in binary variables
(VARB). The hexadecimal value must be specified the same as the binary value—left is least
significant byte, right is most significant. For example, to set bit 1, 5, and 7 you would
issue the command VARB1=h15. Notice that the letter h is required. NOTE: When
assigning a hexadecimal value to a binary variable, all unspecified bits are set to zero.
Example Response
VARB1=h7FAD
VARB1 *VARB1=1110_1111_0101_1011_0000_0000_0000_0000
