Hot Tips from PSG: 64-bit Literals in OptoScript
Opto 22's Product Support Group (PSG) develops some helpful tips as they work with customers who contact them for free product support.
Recently a customer was reminded that there's something special about assigning integer 64 literals to variables in PAC Control's OptoScript—you have to specify that's what they are. If you don't specify, OptoScript assumes they are integer 32s.
Integer 32s are suitable for most applications. But if you need a much larger number or are using an I/O unit with 64 points of digital I/O, you may want the integer 64.
To indicate a decimal integer 64, simply put i64 at the end of the literal, like this:
dVariable1 = 0i64;
dVariable2 = 10i64;
dVariable3 = -123i64;
Similarly, you indicate a hexadecimal integer by putting 0x at the beginning of the literal:
nVariable1 = 0x0;
nVariable2 = 0x12AB34CD;
For a hexadecimal integer 64, you must indicate both the hex format and the i64:
nVariable3 = 0x0000000100000628i64; or
nVariable4 = 0x100000628i64;
By the way, hex formats can use either upper- or lower-case digits A, B, C, D, E, and F.
For more information on OptoScript formats, see Chapter 11, "Using OptoScript" in the PAC Control User's Guide.
You can also find examples in the "OptoScript Examples" strategy, which is installed with PAC Control in a location such as C:\Program Files\Opto22\PAC Project 8.2\Control Pro Examples\OptoScript Examples\
