#line keyword in C

I am trying to understand some code and I've come across a keyword that I've never seen before. I tried to google it, but haven't found anything regarding it as well.

char *valtext;
#line 1 "Values.l"
#define INITIAL 0
#line 2 "Values.l"
int reserve(char *s);
#line 388 "lex.val.c"

I've included the entire block hoping that perhaps someone can help me understand this chunk of code. I can't find any files on my system named "Values.l" and this chunk of code is located in the "lex.val.c" file.

Thanks in advance.
