6502 to Z80 Port

[someone]

I will be more specific

what are the Z80 Microbee equivalents for

!BYTE
!SCR
!PET

!BYTE - just means that some bytes are following.
As per the comments in your example:
$01, $00 = <integer word 1>
$9E = <token for PET BASIC SYS>
$31,$30,$33,$37 = "1037"

!PET - pseudo op for PETSCII String
!SCR  - pseudo op for screen code

These are do not have direct microbee equivalents thus you'll have to formulate your own solution.
 In addition to pure 6502 to Z80 porting, you also have to consider the hardware differences.
