Conditions Calls

Post by madaxe » Fri Jun 25, 2021 5:18 pm

Hi there;

In 8086 assembly is there something like Conditions Calls like the good old Z80? Something like call nc, call nz, etc?

There isn't in 8086, If you want to do a 'conditional call', you should jump over the call statement when the condition is not true

For example if you want to call if Zero:

Code: Select all

    JNZ NoCall
        CALL CallIfZero
    NoCall:

Thank you, Keith! I thought that was something like that :-P
Just ordered your book from Amazon UK. Hope Brexit doesn't bring me many troubles, lol!
