Hello,

So my problem is concerning the following syntax:

String var3.

Compute var3 = CONCAT(var1, var2).

Execute.

var1 and var2 are both string-variables and it is always the case, that when there is a value on var1, there is a missing on var2 and the other way around. '-66' is declarated is a missing.

Now, if var1 = 'text' and var2 = '-66' this is what var3 should look like: var3 = 'text' and this is what it actually looks like: var3 = 'text-66'.

So is there a possibility to achieve, that missings are treated like an empty string? Or do you have an idea where I made a mistake?

Recoding var1 and var2 into numerics isnt possible because they are open answers .

Thank you.

Look at the DO IF command and the MISSING function.
