William: Write me an assembler program using high-level assembler for the mainframe.
Chatgpt: Certainly! Here’s a simple example of a mainframe assembly program written in High-Level Assembler (HLASM) that reads two numbers from input and prints their sum: PRINT NOGEN TITLE 'Simple Addition Program'** Define storage for input numbers and result*NUM1 DS F First input numberNUM2 DS F Second input numberRESULT DS F Result of addition** Main program*MAIN C 0 NUM1 Check if NUM1 is zero BE ZERO Branch to ZERO if true** Read the first number from input* GET NUM1,NUMIN Read NUM1 from input LA 0,NUM1 Load NUM1 into register** Read the second number from input* GET NUM2,NUMIN Read NUM2 from input A NUM1,NUM2 Add NUM1 and NUM2 ST NUM1,RESULT Store the result in RESULT** Print the result* PUT RESULT,NUMOUT Print the result** Terminate the program* SR 15,15 Set return code to 0 BR 14 Return to caller** Define input and output areas*NUMIN DC F'0' Input buffer for numbersNUMOUT DC F'0' Output buffer for resultZERO DC F'0' Constant zero END MAIN End of program Please note that this is a simplified example for demonstration purposes. In a real-world scenario, you would need to adapt this code to your specific mainframe environment and requirements. Assembly language programming can be quite complex, so make sure to consult the documentation for your specific mainframe and assembler to ensure compatibility and correctness. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
