Odp: Re: Data mapping

File 1 has a variable format string of data.  Sort of like a data queue.  It's 
just a character string of varying length.  Within the string (like the first 
few positions) is there a code that let's you know what the string identifier 
or format is?  

Exactly it is.

No, this is EDI aplication. And fixed format of variable/message is given in 
format file.

No, we know the data separator "+" and with this we can tokenize string. File 2 
contains description of each subsequent token. I will paste simplified format 
of this file again:

Tag      Element     Type    ..   Destination File   Destination Field
HDR         1        Num     ..     LOGFILE             FLD1
HDR         2        Char    ..     LOGFILE             FLD2
SND         1        Num     ..     ORDERS              FLD1
SND         2        Num     ..     ORDERS              FLD2
.
.
SND         N        Date    ..     ORDERS              FLDN
ADD         1        Num     ..     DETAILS             FLD1
.
.
ADD         N        Char    ..     DETAILS             FLDN
EOD         1        Num     ..     LOGFILE             FLD3

The goal is to write data from message to files/fields specified in this file 2
