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.
>>>Is this a CGI application where each an every variable can have different
>lengths or is it a fixed format?
No, this is EDI aplication. And fixed format of variable/message is given in
format file.
>>>Now when you talk about file 2, is it a list of from-to positions so you can
>walk down the character string of file 1 and parse out the data or is file 2
>an externally defined file that you can use in your program as a data
>structure and parse by a simple MOVE command or is it a list of keyword/value
>pairs to assist you in parsing?
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
Than You James
