Yes (although more the other way around: Text is a standard Pascal
type, while TextFile is an alias for Text introduced in Delphi).

Normally, you would use plain assign() with Text files, but AssignFile
maps through to that.

Same remark as for assign() here (close vs closefile)
So your error is unrelated to the use of assign(file)/close(file), it
is something else.
