Expression help

Can anyone fill me in on how to translate the pipe symbol below. I am converting some ladder logic (rslogix5) to structured text(rslogix5000) and this particular expression is used in the CPT(compute) instruction. Since there is no cpt instruction in ST im forced to use this (destination := numeric_expression. The only problem im having is an error saying:
Error: Line 15, '|': Unexpected.

This is line 15

//SFilterIntCalculated.FilterIntExponent := (-1.0 * 0.0) | SFilter.FilterTimeConstant;

This is the expression directly from the ladder logic.
//(-1.0 * F135:110) | F259:0

What im using in place of CPT instruction.
destination := numeric_expression;

Any help will be greatly appreciated.

The " pipe" is used for division. So " | " in a PLC-5 = "/" on a keyboard.

Thank you..

Pardon my ignorance but wont SFilterIntCalculated.FilterIntExponent always be 0 due to (-1.0 * 0.0 )

the pipe on the keyboard is this

Ok had to look at it closely, it appears that AB uses the vertical bar | for division; which is what Mickey highligted.

Expressions - The expression is zero or more lines, with up to 28 characters per line, up to 255 characters. Instructions that can be used in the Expression include: +, -, *, |(DIV), SQR, - (NEG), NOT, XOR, OR, AND, TOD, FRD, LN, TAN, ABS, DEG, RAD, SIN, COS, ATN, ASN, ACS, LOG, and ** (XPY). The execution of a CPT instruction is longer than a single arithmetic operation and uses more instruction words.

I think his expression will use an F type data file where 0.0 is, look at what he states is actual code:
//SFilterIntCalculated.FilterIntExponent := (-1.0 * 0.0) | SFilter.FilterTimeConstant;

Since in the SLC500 and PLC5 the '/' character is the bit delineator then for the CPT insturcion it is necessary to use the '|' character to denote division.

Its a matter of N7:0/2 vs N7:0|2 and what each statement means.
