Update Multiline Attribute Definition in block

[Anonymous]

I created a title block with single and multiple lines attribute definitions.

I've written a routine to insert the title block and set all attributes blank.

Then I read a file with attribute name and value.

Then I cycle thru the block and update each attribute with the values.

I can't figure out how to update the multiline attdef.

I tried using subst and entmod/entupd - doesn't work.

I tried using vla-put-MtextAttributeContent - doesn't work.

What am I missing?

(VLA-PUT-TEXTSTRING MYATT "NEW STRING")  worked for me.

I was using vla-put-MtextAttributeContent not vla-put-TextString
