This is only a problem if they are typed on separate lines.

This is a long standing problem, and has been
a low priority.

The problem is that the string that is used
for command line input by the 'executive'
processing still exists when the 'restore'
happens, but this string is brought into
existence after the 'save' operation, thus
an invalidrestore.

We need to move this to Issues.htm.

This bug was modified accidentally removing the customer field.  I'll fix it as
soon as I figure out how to recover the old customer number...

This bug was fixed by the Ray's commit for rev. 6886 and works in released
versions since v. 8.56.
