Not sure if this is the correct forum but here goes.

I have a number of records which contain a calculated text field. I want to be able to perform a find on and then write just this one text field to a text file in the order that it appears in the database.

Since you already are scripting the selection of records could you flip to a layout where only this single field resides, you can then issue a Copy All Records scriptstep, which fills your clipboard with the result in a pilcrow delimited format ready to paste into say a global field.

However does the use of this step tamper with what the user might save in his/her clipboard ... this means that you pre-emptively needs to store what the user might have there. Here would another global container field fit the bill as a second step where it's attempted to store the unknown meta-object in a global text field first, then on fail to store as text continue to the global container field.

Now perhaps some mongering is required to the sample as well, here could it be done either with further scripting or autoenter reformatting.
