Coding scheme Description Valid characters Length
Bin (Binary) Each character in a variable
presents one physical byte Any value a byte can
have (0-255) 1 character = 1 byte of data
Hex (HexASCII) HexAscii encoded binary data 0-9, A-F 2 characters = 1 byte of data
Dual (BinaryASCII) Bitwise encoded binary data (MSB
first orientation) 0/1 8 characters = 1 byte of data
Dec (Decimal) Decimal presentation of numbers 0-9 Variable depending from value of the
number

5.3.3 Functions
Function + syntax Description
DecToBin(expression) Converts decimal part of expression into binary string of bytes. Decimal number in
expression must not exceed 2^64.
BinToDec(expression) Converts expression into decimal number
HexToBin (expression) Converts expression given as hexadecimal number represented in ASCII
characters into binary representation.
HexToBin(„3161“) returns „1a“
BinToHex (expression) Converts expression to hexadecimal string
DualToBin (expression)
Converts dual expression to binary representation.
BinToDual (expression) Converts expression to dual representation
BinToDual(„1a“) returns „0011000101100001“
PadRight(expression, character, number) Pads expression from right with given character until string length is equal to
number
PadRight(“111”,”2”,5) returns “11122”
PadLeft(expression, character, number) Pads expression from left with given character until string length is equal to number
PadLeft(“10101”,”0”,8) returns “00010101”
