Hello,
My apologies if this has been posted elsewhere, I have had a look at several threads but I am still confused how to use these functions. I have two files, each with 5 columns:

I have 20 tab delimited text files that have a common column (column 1). The files are named GSM1.txt through GSM20.txt. Each file has 3 columns (2 other columns in addition to the first common column).

Hi there,
I am trying to join 24 files (i showed example of 3 files below). They all have 2 columns. The first columns is common to all. The files are tab delimited eg

I would like to join two files when two columns in each file matches with each other and then produce an output when taking multiple columns.
Like I have file A
1234,ABCD,23,JOHN,NJ,USA
2345,ABCD,24,SAM,NY,USA
5678,GHIJ,24,TOM,NY,USA
5678,WXYZ,27,MAT,NJ,USA
and file B

Hello all,
I want to join 2 tabbed files on the first 2 fields, and filling the missing values with 0. The 3rd column in each file is constant for the entire file.

tstate
TOPEN(3F)TOPEN(3F)NAME
topen, tclose, tread, twrite, trewin, tskipf, tstate - f77 tape I/O
SYNOPSIS
integer function topen (tlu, devnam, label)
integer tlu
character*(*) devnam
logical label
integer function tclose (tlu)
integer tlu
integer function tread (tlu, buffer)
integer tlu
character*(*) buffer
integer function twrite (tlu, buffer)
integer tlu
character*(*) buffer
integer function trewin (tlu)
integer tlu
integer function tskipf (tlu, nfiles, nrecs)
integer tlu, nfiles, nrecs
integer function tstate (tlu, fileno, recno, errf, eoff, eotf, tcsr)
integer tlu, fileno, recno, tcsr
logical errf, eoff, eotf
DESCRIPTION
These functions provide a simple interface between f77 and magnetic tape devices. A ``tape logical unit'', tlu, is ``topen''ed in much the
same way as a normal f77 logical unit is ``open''ed. All other operations are performed via the tlu. The tlu has no relationship at all
to any normal f77 logical unit.
Topen associates a device name with a tlu. Tlu must be in the range 0 to 3. The logical argument label should indicate whether the tape
includes a tape label. This is used by trewin below. Topen does not move the tape. The normal returned value is 0. If the value of the
function is negative, an error has occured. See perror(3F) for details.
Tclose closes the tape device channel and removes its association with tlu. The normal returned value is 0. A negative value indicates an
error.
Tread reads the next physical record from tape to buffer. Buffer must be of type character. The size of buffer should be large enough to
hold the largest physical record to be read. The actual number of bytes read will be returned as the value of the function. If the value
is 0, the end-of-file has been detected. A negative value indicates an error.
Twrite writes a physical record to tape from buffer. The physical record length will be the size of buffer. Buffer must be of type char-
acter. The number of bytes written will be returned. A value of 0 or negative indicates an error.
Trewin rewinds the tape associated with tlu to the beginning of the first data file. If the tape is a labelled tape (see topen above) then
the label is skipped over after rewinding. The normal returned value is 0. A negative value indicates an error.
Tskipf allows the user to skip over files and/or records. First, nfiles end-of-file marks are skipped. If the current file is at EOF, this
counts as 1 file to skip. (Note: This is the way to reset the EOF status for a tlu.) Next, nrecs physical records are skipped over. The
normal returned value is 0. A negative value indicates an error.
Finally, tstate allows the user to determine the logical state of the tape I/O channel and to see the tape drive control status register.
The values of fileno and recno will be returned and indicate the current file and record number. The logical values errf, eoff, and eotf
indicate an error has occurred, the current file is at EOF, or the tape has reached logical end-of-tape. End-of-tape (EOT) is indicated by
an empty file, often referred to as a double EOF mark. It is not allowed to read past EOT although it is allowed to write. The value of
tcsr will reflect the tape drive control status register. See ht(4) for details.
