Description	These assembler files contain various math functions for 8051 and compatible microcontrollers: The file MATH32.A51 contains code for the following 32-bit math functions: Add a 16-bit value to the 32-bit 'accumulator'. Add a 32-bit value to the 32-bit 'accumulator'. Subtract a 16-bit value from the 32-bit 'accumulator'. Subtract a 32-bit value from the 32-bit 'accumulator'. Multiply the 32-bit 'accumulator' by a 16-bit value. Divide the 32-bit 'accumulator' by a 16-bit value. The file DIV16BY8.A51 contains code to divide a 16-bit dividend by an 8-bit divisor and produce a 16-bit quotient and an 8-bit remainder. The file LONGDIV.A51 contains code to divide an N-byte dividend by an N-byte divisor and produce an M-byte quotient.

how can subtract 23hex from 78hex for 8051 by asm51 code please help me.

how can subtract 24hex value from 78hex value for 8051 by asm51 , so please help me.

@samarnath dev, both 0x23 and 0x78 are 8-bit values, use simple "SUBB" instruction to subtract them. Move one value in A and other in R0 or you can give direct data. Post in forum for help.
