[fpc-pascal] How to eliminate specific hint (was: how to initialize a SearchRec var?)

I would suggest to use the following sequence instead:
=== code begin ===
{$push}
{$hints off}
// whatever
{$pop}
=== code end ===

  The is a more specific way to remove a given hint:

Use -vq option to get the numeric value of the message:

E:\pas\test>ppc386 -vhq tsearchrec.pas
Hint: (11030) Start of reading config file
e:\pas\fpc-2.7.1\bin\i386-win32\fpc.cfg
Hint: (11031) End of reading config file
e:\pas\fpc-2.7.1\bin\i386-win32\fpc.cfg
tsearchrec.pas(13,20) Hint: (5058) Variable "dirinfo" does not seem to be
initialized

Disable that specific message by using -vm option:

E:\pas\test>ppc386 -vh -vm5058 tsearchrec.pas
Hint: Start of reading config file e:\pas\fpc-2.7.1\bin\i386-win32\fpc.cfg
Hint: End of reading config file e:\pas\fpc-2.7.1\bin\i386-win32\fpc.cfg

Magic, isn't it?
