This looks like 8080 or Z80 assembly. It has been a while since I have done anything related to that processor so I might be wrong. Here is my interpretation:
MOV A,#15 /* Move number 15 to register A */
MOV B,#23 /* Move number 23 to register B */
Loop CMP A,B /* Compare A with B. Loop is a label used later */
JAE LpDone /* If above or equal, jump to label LpDone */
ADD A,#101 /* Add number 101 to register A */
JMP Loop /* Jump to label Loop */
LpDone NOP /* LpDone is label. NOP is no-operation so it does nothing. */
