MRGCOPY


MRGCOPY is a program which copies one Merge-format file to another.   It
is  not  intended  for  normal  use:   it  is easier to use the DCL COPY
command.  Rather, it serves as a skeleton program which  can  be  easily
modified  to  perform some operation on the data in the merge file.  One
may copy the source code, modify it to do the job, recompile it, and run
it, as follows:

$ COPY VLBSOURCE:MRGCOPY.FOR []SPECIAL.FOR
$ EDIT SPECIAL.FOR
 ...
$ FORTRAN SPECIAL
$ LINK SPECIAL,VLB:VLBLIB/LIB
$ RUN SPECIAL

In order to modify the program one  will  need  some  knowledge  of  the
structure  of  merge-format files, which is described in Appendix A (see
VLBHELP FORMAT).


Example

$ MRGCOPY
INPUT  = [SCRATCH]3C179P.MRG
OUTPUT = 3C179Q.MRG
/
$
is equivalent to
$ COPY [SCRATCH]3C179P.MRG []3C179Q.MRG


Parameters

End the list of parameters with a slash (/).  Quotation marks  are  only
needed if the value includes spaces or commas.

INPUT = filename :  specifies the name of the input file.

OUTPUT = filename :  specifies the name for the output file.

HISTORY= "text" :  the specified text (up to  80  characters)  will  get
          written in the history of the output file.


History

Version 1.0:  1984 May 2 (T.J.  Pearson).
Version 1.1:  1985 Jul 24 - add HISTORY parameter, and remove the sample
          code that erroneously changed UT in each record (TJP).
