Format

⍕

Format (⍕) is a primitive function.

Examples

Format in its monadic form, alongside ravel, allows the user to concatenate numbers with strings:

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

It is very powerful when combined with execute, which allows the user to interpret a string as APL code:

       data ← 7
       ⍎'6 × ',⍕data
