Breakpoints may also have a conditional statement that causes them to execute only if that statement evaluates to true. The conditional breakpoint grammar has this form:
+ a J( A7 B' A5 s% z! R1 g, W9 g
9 b. d5 p m, OConnect -> Compare { ('||' | '&&') Compare }
0 ]9 V9 x+ B+ c" L- qCompare -> Sum { ('==' | '!=' | '<=' | '>=' | '<' | '>') Sum } 8 I# ]8 g% R. \
Sum -> Product { ('+' | '-') Product }

The parser is very strict. All numbers are hexadecimal. Always prefix a number with # for an immediate value, or $ for a memory address. If a memory address needs to be calculated use $[] with the calculation inside the brackets.9 A, t3 y4 {6 `, ^9 i, t: d
