I don't need it outside of the while loop. All right, um, so I'm going to go ahead and use a variable called bit. So I'm going to say, while the small number is greater than zero, that means I'm not done yet. And so I'm just going to keep ah processing decimal number and making a smaller processing making smaller. And then I'm going to go ahead and just create a verbal called hex numb, and I'll make it up, get a string, and that will be the the output. So we're going to say, enter a decimal integer and we get that decimal imager from the user. Looks like, if not, hopefully this will help. Or just use jmp Ale for last one without cmp, so it will do that for any-other-input.All right for this problem, we're going to enter a decimal number and convert it to a ah Hexi decimal, which is based 16.

You can fix all those jmp to be cmp+je, and add after last JE Ale another code reporting invalid input value (outside of 1.4 range). So if you want jump to Ale for AL containing value 4, you can do similar test like for first one: CMP AL,4 In case this would be some count-down loop with early exit after zero is reached in counter, then jz alias is more accurate for source reader.

And JZ instruction is the same one, the JE is just its alias for better semantic reading of source, showing intent of programmer more accurately, like in this case you want to jump because AL was equal to 1, not because there was some zero involved (although there was, because 1 - 1 = 0). JE is acronym of 'jump equal', which internally works as 'jump when ZeroFlag is set'. The CMP instruction will calculate subtraction ( temp = AL - 1), in the exactly same way as SUB instruction, but the result value is discarded (not stored anywhere, in this case AL remains intact), and only flags are updated. If it's possible for Call GETINPUTS to return more than the valid choices, then you need to guard against this by writing defensive code especially avoiding to fall through in the beneath code. Given that the values are known to be in the range, you can replace the pair cmp al, 2 je IPABeer2 with a simple jmp IPABeer2. This way you can omit the cmp al, 1 instruction. If, when comparing with the value 2, you find that the Carry Flag is set, then you know that the value in AL was below 2. Now we can reduce the number of comparisons even further by investigating more than just the Zero Flag (testing for equality). You can replace the pair cmp al, 4 je Ale with a simple jmp Ale. Given that the values are known to be in the range, the 4th comparison is not needed since it will always jump. The naive approach would be to test for each case like in next snippet: BeerTypes: Let's presume that the Call GETINPUTS gives valid choices in both Inputs (1, 2, 3, or 4) and Inputs (1 or 2).

If anyone knows how to fix this problem, I would really appreciate knowing why this is happening. For the initial question, I ask the user to select a choice from 1 to 4, but the third and fourth choice do not work. For a school project, I was told to create a program that asks a user two questions and each question has multiple choices.
