lcnt [file] ...
.ds
lcnt counts the number of lines of text in the named input files, or the 
standard input if no files are given
or the filename '-' appears.
A line is zero or more characters terminated by a NEWLINE marker.
 
lcnt could also be implemented as a shell script file:
 
.ce
tr '!@n' | ccnt
.fl
.sa
ccnt; wcnt; the Unix command 'wc'
.di
A message is printed if an input file could not be opened;
processing is terminated.
