The symbol for the assignment operator in Pascal is := instead of =.

Pascal uses single quotes for a quoted string e.g. writeln('Hello World!') .

The string concatenation symbol is + in Pascal instead of & in VB.

Whereas VB uses a new line or a colon to separate statements, Pascal uses a semi-colon. A Pascal statement may span lines without the use of a continuation symbol, but a quoted string spanning lines must be split into substrings e.g.

writeln('This is a long quoted string ' +
        'spanning two lines.'); 

Array indices in Pascal must be in square brackets not round brackets as in VB.

The ^ symbol for exponentiation is not available in Pascal. (Pascal uses the Power function in the Math unit).

A one line comment is preceded by // in Pascal and a multi-line comment is enclosed in braces.
