the ℕ𝕠𝕞 "count" command

The count command adds the value of the counter variable to the end of the workspace buffer.

For example, if the counter variable is 12 and the workspace contains the text 'line:', then after the count command the workspace will contain the text

print line numbers before each line

 read; [\n] { a+; count; add ": "; }  print; clear;

run the line-numberer with the ℙ𝕖𝕡 interpreter

 pep -e "read; [\n] {a+; count; add ': '; } print;clear;" filename

the same line-numberer with cryptic single char commands

 pep -e "r;[\n]{+;n;a': ';}t;d;" filename

translate this one-liner to java, compile and run



    pep -f tr/ ??translate.java.pss \ ??
      -e "read; [\n] {a+; count; add ': '; } print; clear;" > Machine.java
    javac Machine.java
    cat / ??usr/ ??share/ ??dict/ ??words | ?? java Machine

note: it would be simpler to use the lines command in this example

print line number before each line with "lines" command

 read; [\n] { lines; add ": "; } print; clear;

count the number of dots in the input

 read; "." { a+; } clear; <eof> { count; print; }

The count command only affects the 'workspace' buffer in the Pep virtual machine . The pep machine also maintains an automatic count of the

For counting lines and characters in the input-stream, the commands lines chars", “nolines” and “nochars” exist.

count blank lines in input



    read; 
    "\n" { 
      while [ \t\r]; clear; 
      !(eof) { read; "\n" { a+; }}
    }
    clear;
    (eof) {
      add "Blank lines: "; count; add "\n";
      print; quit;
    }
