When asking for help, it's also always a good idea to provide all information that may be relevant, such as the actual command line you are using and platform you are on.

On Linux:

$ fpc -h |head -12
Free Pascal Compiler version 2.7.1 [2012/07/17] for sparc
Copyright (c) 1993-2012 by Florian Klaempfl and others
/usr/local/bin/fpc [options] <inputfile> [options]
Put + after a boolean switch option to enable it, - to disable it
   -a     The compiler doesn't delete the generated assembler file
       -al        List sourcecode lines in assembler file
       -an        List node info in assembler file (-dEXTDEBUG compiler)
       -ap        Use pipes instead of creating temporary assembler files
       -ar        List register allocation/release info in assembler file
       -at        List temp allocation/release info in assembler file
   -A<x>  Output format:
