  dlmake - log creation of logical RMSfile
  SYNOPSIS
  #include <cbase/dbase.h>
  #include <cbase/logfile.h>
  dlmake (lname, nrecs, deffile)
  char *lname, deffile;
  long nrecs;
  DESCRIPTION
  Dlmake records a marker in the current log file to create a logical RMSfile with a given size and format. The new RMS definition file is also written to the log file. When the restore program, drestore(C-1), encounters this marker, it creates a new logical RMSfile.
  Lname is the name of the logical RMSfile. It can have any of the following formats:
  dbase~lfile
  ~lfile
  lfile
  The first form names an explicit database, the latter two use the default database. A default database is defined by calling dbopen(C-3), or setting the environment variable DBASE to a valid database name.
  If a path name (a name containing slashes (\ or /)) is passed to dlmake, no entry is made in the log file.
  Nrecs is the new RMSfile size in records.
  Deffile names an RMS definition file to be copied into the log file.

  DIAGNOSTICS
  A value of FAILED (0) is returned if the marker cannot be written in the log file. The RMS error message is set describing the error.
