*ERROR 146 -- a string constant may not extend over more
than one line
This error is issued when a line-break is found inside a string constant. It is
usually caused by omitting the closing quote of the string.

Writeln('the final quote is missing);
*ERROR 147 -- strings of differing lengths may not be compared

the same number of characters.

IF 'cat' > 'mouse' THEN writeln('bigger');
*ERROR 159 -- an underline is required between a machine-code
mnemonic and its operands

the first operand. Machine-code is an extension to standard Pascal.
