i have one question which puzzled me for a long time.
R:E 00000 3650 USING DFHCWADS,R14
0013CC D703 E2C0 E2C0 002C0 002C0 3651 XC CWADASH,CWADASH
3652 DROP R14
As the above code shows, both USING and DROP don't generate objective code, so when these code were executed, how does the computer know USING and DROP's purpose? In other words, where does this information(USING/DROP) store? how to deal with it by the computer?
