Assembly Version
LDR R0, #0 .loop ADD R0, R0, #1 CMP R0, #99 BNE .loop
Line 1 sets the value of Register 0 to the value 0.
Line 2 is a label which will be used to branch too.
Line 3 adds the value 1 to the current value in Register 0 and stores the value back into Register 0.
Line 4 compares the value in Register 0 with the value 99.
Line 5 will branch to the .loop label if the previous compare was NOT EQUAL.
