are you trying to copy from a string in the program or in a variable?
ldir mean "load, increment, and repeat"
it copies bc bytes from (hl) to (de)
from z80iss.txt:
+------------+--------------------+------+---+---+----------------------+
|LDI |(DE):=(HL); |..*.00| 2 |16 |PV=0 if BC=0,else PV=1|
| |inc DE,HL;dec BC | | | | |
+------------+--------------------+------+---+---+----------------------+
|LDIR |Repeat LDI |..0.00| 2 |21 | |
| | until Z=1 or BC=0 | | |16 | |
+------------+--------------------+------+---+---+----------------------+
i got a "z80time.txt" file somewhere that includes the hex codes, there's
another one that also has undocumented instructions.
