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 42
