Synopsis
Official Name: OP1,OP2,OP3,OP4,OP5,OP6,OP7
Memory Address: D005F8h - D00644h
Length: 11 bytes each; 77 bytes total
These
This area is divided into seven 11-byte registers:
- OP1 = D005F8h
- OP2 = D00603h
- OP3 = D0060Eh
- OP4 = D00619h
- OP5 = D00624h
- OP6 = D0062Fh
- OP7 = D0063Ah
Among the many functions the OP registers are used for:
- A single OP register can hold an 11-byte floating point number.
- Two adjacent OP registers -- usually OP1 and OP2, OP3 and OP4, or OP5 and OP6 -- can hold a 22-byte complex number.
- The first 9 bytes of an OP register can hold a variable name.
- OP3-OP6 are used for storing short strings.
- All 6 OP registers can be used together to hold a single big integer.
- The seventh OP register is only used when finding Image variables in RAM. It can generally be used as scrap.
