Other Syntax Issues

This line of code does not run properly in if else endif statements due to the {((%SUB_CODE%"l")OR(%SUB_CODE%"p"))}

However if I run this code and change the functionality in the if else endif statements, it runs OK

If>{((%SUB_CODE%="l")OR(%SUB_CODE%="p"))}

Any ideas why?

Remove leading {((%SUB_CODE%"l")OR(%SUB_CODE%"p"))}

Don't you mean:

If>{((%SUB_CODE% "l") AND (%SUB_CODE% "p"))}

i.e. SUB_CODE must be anything other than I or P?

Mixing not equals and OR is a common mistake. OR means either one of the conditions can be true. If SUB_CODE is "p" then the first condition is true. While the second is not true the entire expression is true because each part is ORd. If SUB_CODE is "l" then the first expression is not true but the second IS true, so the entire If resolves true. Using AND ensures that ALL expressions must be true. Therefore it works if SUB_CODE is "l" or "p".
