[error] Internal variable "!COLx" not supported - how to avoid CSV read error?

A link to source ticket ^^^^

Based on that idea i implemented cycle reading the file, but i am stuck in this moment:
when !COLx is pointing to not existing element, it breaks the macro, and !errorIgnore doesn’t help.
I was expecting !errorignore avoids this error and i can go further, but no =)
I tried store and storeEval commands, same result.

Here is a screenshot: http://i.prntscr.com/JPEVGh62QuihN5hzEaMuLw.png

sample CSV lines:
Propriétaire,QR,Non,Non-applicable,Non-applicable,Non-applicable,
Propriétaire,SICA,Non-applicable,Non-applicable,Non-applicable,Non-applicable,
Courtier,SICA,Non-applicable,Non-applicable,Non-applicable,Non-applicable,

And actually macro:

Just to clarify

Just to clarify: Why is the element missing?

  • Is the column missing altogether?
  • or your CSV file is just one large row that you want to read step by step?
  • or… ?

because there is no more columns in this file’s line, there are only 7.
i am trying to read the line with undefined amount of columns ( i expect maximum 9 columns in my macro for now).
In example i’ve provided (see above) there are 7 elements, and when 8-th element is requested - it gets an error, and i can’t avoid it.
Maybe you know better way to handle this case?
