Delphi/Lazarus: Using Apostrophes ' in String

When defining a string, the string is separated with an apostrophe on both sides, for example s := 'abc'. If you are now using an apostrophe within the string, the compiler only sees this delimiter character and things that your string ends at this place. So, the compiler complains about anything coming thereafter.

Solution: You have to double each apostrophe that is part of your string within your string. Here is an example:

s := 'ab''cd';

This string would be interpreted as ab'cd.

Alternatively, you can also use #39 instead of the apostrophe character:

s := #39'abc'#39;
s := #39+'abc'+#39;
s := 'ab'#39'cd';

This example, the first two rows would both result in the string 'abc' while the third line is ab'cd.
