CNV allows you to perform the following functions: 1) create a new Sequential file from the records of an existing Sequential, Relative, or Indexed file. 2) supersede an existing Sequential file with the records of another Sequential file or the records of a Relative or Indexed file. 3) append to a Sequential file the records of another Sequential file or the records of a Relative or Indexed file. 4) write into an existing Relative or Indexed file the records of another file of any organization. Note that IFL is the fastest, most direct, and most efficient method of populating an empty RMS-11 Indexed file. Type HELP IFL COMMAND for an explanation of its command line and switches. Type HELP CNV COMMAND for an explanation of CNV's command line and switches. 2 COMMAND The general form of CNV's command line is: outfile[/switch(s)]=infile[/switch] Switch Type Description Default ?
