⍕

Format (⍕) is a primitive function.

Examples

Format in its monadic form, allows the user to convert arrays of any type into simple character arrays (for example for concatenation with other character arrays): 

      supper ← 10
      'I ate ',(⍕supper),' shrimp.'
I ate 10 shrimp.

It is very powerful when combined with Execute, allowing the user to construct APL code: 

       data ← 7
       ⍎'6 × ',⍕data
