In the advanced macro format, rules for representation of strings, etc.

If you have chosen the advanced macro format, use the following rules for input fields on the Description tab, Actions tab, and Variables tab:

All strings must be written enclosed in single quotes. Examples:
```
'apple'
'banana'
'To be or not to be'
'John Smith'
```
The single quote (') and the backslash (\) are represented by the characters themselves preceded by a backslash. Examples:
```
'New Year\'s Day'
c:\\Documents and Settings\\User
```
The following characters or character sequences are treated as operators:
- String concatenation operators: +
- Arithmetic operators: +, -, *, /, %
- Conditional operators: ==, !=, >, <, >=, <=
- Logical operators: &&, ||, !
