Check_Bit
Syntax: Check_Bit(inputString, inputStringDataType, position)
Arguments:
- inputString is the original string to be checked.
-
inputStringDataType is the input string data representation. Valid values are:
0 or HEXADECIMAL_DATA, if the inputString is a hexadecimal representation (length of inputString must be divisible by 2)
1 or BINARY_DATA, if the inputString is binary (length of inputString must be divisible by 8)
2 or STRING_DATA, if the inputString is a string representation
- position is the position of the inputString to be checked from left. It is 1-based index. The value of this field is in binary representation position.
Return Type: Integer
1: Bit position is 1
0: Bit position is 0
-1: Invalid position value or inputStringDataType
-2: Invalid inputString
Description: This function will check if the bit position in inputString parameter is 0 or 1.
Example:
returnCode is an integer;
returnCode = Check_Bit(CRTRAN25.terminalVerificationResults, HEXADECIMAL_DATA, 8);
if(returnCode = 1) then
{
TriggerCase(SERVICE);
}
In this example, the Check_Bit function checks if bit 8 of terminalVerificationResults is 1 or 0. A service case is triggered if the bit in position 8 is 1.
