Displaying a number which have 2 digits in Assembly

[quartaela]

hi there i am working on a project with assembly programming and i am facing with a problem about displaying a number which have 2 digits. the main problem is if i have one digit number i can display but if i have 2 digit number the program displays the first digit. here is an example code which is in a subroutine. i used ASRA, LSRA and RORA but i can't fixed this problem.


DISPA:
JSR CLEARD

LDAA 20H
JSR PATCON
LDAB #40H
JSR DISPAT

LDAA 20H
CMPA #0FH
BLT DISPALEVEL1
ASRA
LDAB #80H
JSR DISPAT

DISPALEVEL1:

and the second problem is BLT code isn't working correctly. assume that in 20H there is a number bigger than 0FH, so it must be a 2 digit number. and if it is less than 0FH it must branch to DISPALEVEL1 but it executes the code above BLT if i replace BGT when the number is bigger than 0FH.

so how can i fix this problem_?. and thanks for your help anyway. : )

Which processor is this for? I think one cannot say "Assembly", like one can say "C", because it's not generally universal. i.e. I am familiar with NIOS II assembly, and some of your commands I have never seen before.
But I think the "flavor" of assembly might help us understand what the code does.

upps i forgot this thread. anyway i solved the problem : ). Layers we are using motorola 6800 emulator for programming assembly language. and sorry for late answer :)

No problem. I suspected it, but wanted to be sure.
Can this thread be marked as solved?
