Dear Oliver,
Could you be more specific about what you actually want to implement. Maybe you could provide some screenshots of your idea and why it is not working (or the .abl file if possible) so that it is easier for others to understand and test your implementation.

Dear Oliver,

thank you for the detailed description. This helped to better understand your issue. In order to make the object height changeable depending on the attributes you can do the following:

1) Draw the implementation header (line 54-70) after the last SET dim_height statement in line 215. As a consequence, the object will be drawn with the height defined at the end, which depends on the attributes.

2) Use the min() and not the max() function in line 215.

3) When you create new attributes they are usually empty by default. Depending on the type this can be "" e.g. for Strings and 0 e.g. for integers. This means that you do not have to set a default value “empty”, but you can just check in the if-statement if the attributes are empty. E.g. if the attribute "purpose" is a String in your case then the if-statement in line 164 would look the following: IF(var_purpose != "") {}. As I do not have your library, I tried to recreate the depicted object and made the assumption that all the attributes you used are Strings. Thus, for the script I attached all the if-statements are adjusted to String attributes. Depending on the type of the attribute you will have to change the if-statements.
