Hexadecimal Literals
Hexadecimal literals may be used to define unicode strings or numeric values using hexadecimal notation. ASCII or EBCDIC hexadecimal strings are not supported.
Unicode Strings
The format for unicode strings is U"..." where the string between quotes must have a length that is multiple of 4. Each group of 4 hex digits in the string represents the Unicode value of a character. For example, U"00480065006C006C006F" represents the string "Hello".
Numeric Values
The format for numeric constants in hex is H"...". Hex numeric constants are integer values, and the size of the integer depends on the number of digits within the quotes:
- 1 - 2 digits represent a byte value
- 3 - 4 digits represent an 2-byte integer value
- 5 - 8 digits represent a 4-byte integer value
- 9 - 16 digits represent an 8-byte integer value
For example, H”00000032” is the value 50 as a 4-byte integer, whereas H”0032” is the value 50 as a 2-byte integer.
Example
MyString = "Hello" + U"0009" + "World" // U"0009" is TAB character
Number2 = Number1 + H"64" // add 100 (64 in Hex) to Number1
DclConst myTab value( U"0009") // Tab constant
DclConst myNumber value( H"7FFF") // 32767
