Dear All

I am now learning IBM Assembler Basics!

I have an issue but cannot resolve it.

I have a table stored in memory [ x1 , y1 , x2 , y2 , x3 , y3 ]

and I want to loop this table and check y1 or y2 or y3 if equal 25 or not?

if I found y1 or y2 or y3 = 25, I want to exit the loop.

Thanks and waiting your help.

I am working with IBM System VSE/ESA System 390.

More advanced programmers tend to prefer something like this -
In both loops, register 1 is set to the test condition, Another way to code the test would be -
