/* Add a file label and a few documents.
file label This is a test file label.
document First line of a document
This is the second very long line of a document in an attempt to overflow the input buffer with a really long line
Note that the last line should end with a period: .

/* Save the active file then get it and display the documents again.
save 'foo.save'.

display documents.

/* There is an interesting interaction that occurs if the `execute'
/* command below. What happens is that an error message is output
/* at the next `save' command that `foo.save' is already open for
/* input. This is because the `get' hasn't been executed yet and
/* therefore PSPP would be reading from and writing to the same
/* file at once, which is obviously a Bad Thing. But `execute'
/* here clears up that potential problem.

/* Add another (shorter) document and try again.
