SECTION V-6: Using EQU for Fixed Data Assignment
To get more practice using EQU to assign fixed data, examine the following:
| ;In Hexadecimal | |
| DATA1 EQU 39 | ;hex data is the default |
| DATA2 EQU 0x39 | ;another way for Hex |
| DATA3 EQU 39H | ;another way for Hex |
| DATA4 EQU H'39' | ;another way for Hex |
| DATA5 h'39' | ;another way for Hex |
| ;In Binary | |
| DATA6 EQU b'00110101 | ;binary, 35 in Hex |
| DATA7 EQU B'00110101 | ;binary , 35 in Hex |
| ;In Decimal | |
| DATA8 EQU D'28' | ;decimal number, 1C in Hex |
| DATA9 EQU d'28' | ;second way for decimal |
| ;in ASCII | |
| DATA10 EQU A'2' | ;ASCII characters |
| DATA11 EQU a'2' | ;another way for ASCII character |
| DATA12 EQU '2' | ;another way for ASCII character |
We use DB to allocate code memory locations for fixed data such as ASCII strings.
