COMMA.DOC


The program Comma.pcd is a menu exit that make it possible to import Comma
Delimited Files (CDF) into a MicroIsis data base. A field selection table (FST)
is needed to convert data order to file tags. This fst must have as data
extraction format the field command, and the field separator character
(enclosed by vertical bars |) in repeatible fields. The only indexing technique
supported is 0 (whole field).

To export records to CDF, you should use the printing services and define a
printing format which separates with commas fields enclosed by double quotation
marks.



For example, to import the following CDF:

"Helliger, W./Lindner, H.","Biochem J","1992","288"," Part 3","747-751"
"Kohse, K.P./Feifel, K.","Eur J Clin Chem Biochem","1992","30","12","837-845"
"Krishnaraj, R./Svanborg, A.","J Cell Biochem","1992","50","4","386-391"


to a data base with this field definition table:

_  tag    name                len  typ  rep  delimiters/pattern
---------------------------------------------------------------
-   10  Authors               100   X    R
_   20  Journal                50   X
_   22  Year                   10   X
_   24  Volume                 30   X
_   26  Issue                  30   X
_   28  Pagination             50   X
________________________________________________________________


you should use the following reformatting fst:

10  0  v1 |/|
20  0  v2
22  0  v3
24  0  v4
26  0  v5
28  0  v6



To export records from this data base to CDF you can define a printing format
like this:

'"',v10+|/|,'","',v20,'","',v22,'",",v24,'","',v26,'","',v28,'"'/

[ the string '"' is: single quote-double quote-single quote
  and  '","' is: single quote-double quote-comma-double quote-single quote ]
