I think your explanation is not correct @10:05. catch command always returns 1 if there is error. So the first if loop is not executed because the catch command was returning 0 and there is no issue with the exec command. And inside the else loop catch [exec pwd] is throwing error. that's why it is retruning 1 and else loop is executing.

Can you send the modified code with explicit print/puts command, as done by you, at [e-mail]

[@jahnuchoudhury6677]

@@TechSimplifiedTV sure .. sending it

[@shendocodm5196]

Could you explain why in IF_Block1 if statement you use catch {exec pwd} ret but in else you use catch [exec pwd]. It leads to different result. When you catch {} the result is 0 and when you catch [] the result is 1 ? Thank you Sir

Why for every namespace we will use eval ?

[@TechSimplifiedTV]

Hi Krishna , This Time Can you Find out the Answer & Reply back ? Asking because this will make your Learning Curve Sharp !

[@krishnakittu6637]

@@TechSimplifiedTV Sir, as per my understanding using eval we can create new commands in the same way we are using eval with namespace because the namespaces are like implementing a particular function its like a new command that we are creating so we are using eval command when creating a namespace. (Correct me If I am wrong)
