I am a beginner with Lazarus and Freepascal and so please forgive me
my stupid questions.

Right now I want to build a string which has to contain the hex value
'5c'.
I tried hex() but this function does not exist. Is there something I
can use ?

you can use IntToHex() or Format('%x', []);

Okay, I would like to use inttohex.
But how can I find out in which unit it is ?
I tried to search this command with grep.
I can't find it....

It's in SysUtils wich is probably already declared in the uses section
if you are making a default GUI Lazarus application.
It would be useful if you had some delphi books/demos, Lazarus has
more or less the delphi classes and units, but you could get lost in
those include directives.
To check if your function is in the uses section press
[CTRL]+[LEFT_MOUSE_CLICK] and you'll see where it's declared.
