hl isnt a flag, its a 16-bit register pair used in operations
ex:
you can load a 16 bit number into it
ld hl,$2342
or a string
ld hl,(string)

string:
 .db "string",0

you can also use h and l alone
ld h,$23
ld l,$45
this way hl would be a 16 bit number when used together, but an 8bit
number when used alone
