For this task, we want to know the value of n for n-isograms. This value would be zero for words which are not n-isograms. We can implement this by counting how many times each character occurs and determining whether that value is unique. (If it's the unique value, n is the number of times the first character occurs):
<syntaxhighlight lang="j">isogram=: {{ {. (#~ 1= #@~.) #/.~ y }} S:0</syntaxhighlight>
Also, it's worth noting that unixdict.txt is already in sorted order, even after coercing its contents to lower case:
<syntaxhighlight lang="j"> (-: /:~) cutLF tolower fread 'unixdict.txt'
1</syntaxhighlight>
With this tool and this knowledge, we are ready to tackle this task (the /: expression sorts, and the #~ expression selects):
<syntaxhighlight lang="j"> > (/: -@isogram,.-@#@>) (#~ 1<isogram) cutLF tolower fread 'unixdict.txt'
