* Global and permanent variables will not be written unless explicitly specified.
* To write only selected variables, the word EXCEPT may be inserted to indicate all variables except those following EXCEPT.
* If the output file specified does not exist, the WRITE command will attempt to create it.
* Either APPEND or REPLACE must be specified to indicate that an existing file/table by the

* For Epi 6 REC or Access/EpiInfo table outputs, if there are no records,
