This example shows one way to merge the contents of two files and then create a set of new files that organize the data in a new way.

To create the data files

  1. Copy these names into a text file that is named names1.txt and save it in your project folder:

  2. Copy these names into a text file that is named names2.txt and save it in your project folder: Note that the two files have some names in common.

Divide

Example

The program writes a separate file for each group in the same folder as the data files.

Compiling the Code

Create a C# console application project, with using directives for the System.Linq and System.IO namespaces.

There are some old DOS command-line PROGRAMS (e.g., SLICE and
SPLICE from PC-Magazine come to mind) to chop up and reassemble
large files. If you look around, you will find LOTS of programs to do
this. Why not just use WinZip or PKZIP?

To do this in (some kind of) BASIC, you basically read the input file a
byte a time and write each output file a byte at a time, incrementing the
bytes written counter, until the count of bytes written is equal to the desired
number of bytes, then close that slice file, reset the bytes written counter
to zero, open the next slice file and write a byte from the input file until the
count of bytes written is equal to the desired number; keep doing this until
you encounter EOF on the input file, then close all files and exit. The output
files are declared with a record length of one.

Here's an example QBASIC (that's the interpreter, not QuickBasic) program
that splits a large file into multiple files by records (or lines):

begin file c:QBASPGMSSPLIT04.BAS
001. DIM Inrec AS STRING
002. DIM Infile AS STRING
003. DIM OutFile AS STRING
004. DIM MsgFile AS STRING
005. DIM OutFname AS STRING
006. DIM FileSeq AS STRING
007. DIM RecsInFile AS LONG
008. DIM i AS LONG
009. DIM ctr AS INTEGER
010.
011. Infile = ENVIRON$('INFILE')
012. OutFile = ENVIRON$('OUTFILE')
013. MsgFile = ENVIRON$('MSGFILE')
014. RecsInFile = VAL(ENVIRON$('RECS_PER_FILE'))
015. ctr = 1
016.
017. OPEN Infile FOR INPUT AS #1
018. OPEN MsgFile FOR OUTPUT AS #3
019. DO
020. FileSeq = '000' + MID$(STR$(ctr), 2)
021. FileSeq = '.' + RIGHT$(FileSeq, 3)
022. OutFname = OutFile + FileSeq
023. OPEN OutFname FOR OUTPUT AS #2
024. ON ERROR GOTO NOFILE
025. FOR i = 1 TO RecsInFile
026. LINE INPUT #1, Inrec
027. PRINT #2, Inrec
028. NEXT i
029. NOFILE:
030. CLOSE #2
031. PRINT #3, 'Created file ', OutFname
032. ctr = ctr + 1
033. LOOP UNTIL (EOF(1))
034.
035. CLOSE
036. SYSTEM
end file c:QBASPGMSSPLIT04.BAS
