This template is used to list an APL function having 5 lines. If this wiki adds the Parserfunction feature, this template will be replaced by a generic one.

This allows you to list the contents of a function without having to include the line numbers and the ∆ prefix and suffix. You just list the header and the 5 lines. Because of the feature for translating apl symbols, you must specify the line values, Like this:

{{APLFN5|top=⎕vr 'Header'
|header=K←Header arg1
|1='Line1'
|2=X←0
|3=rhoresult ← ⍴ X
|4=⍝ one more line
|5=K ←1 }}

And you get:

    {{⊤}}
    ∇ {{{header}}}
[1]    {{{1}}}
[2]    {{{2}}}
[3]    {{{3}}}
[4]    {{{4}}}
[5]    {{{5}}}
