  1. Associated Processor 15: Structured Storage David Liebtag Title slide

  2. Associated Processor 15 • Strong data typing • Structured storage • Arrays outside workspace • Arrays larger than workspace (for C1, C4, I4, E8, and J16) • External function parameters • Naming elements of arrays Basic text slide

  3. Associated Processor 15 – Syntax Pattern 15 ⎕NA 'VarName' (Pattern Library) 15 ⎕NA 'VarName' (Pattern Address) 15 ⎕NA 'VarName' ('ADDRESS' 'VarName') 15 ⎕NA 'AddrName' Pattern: '[count] type rank [shape]' Library: Name of library (DLL) containing exported variable Address: Address of memory containing data Basic text slide

  4. Associated Processor 15 – Patterns Sample patterns: 'I4 0' ⍝ Integer scalar 'C1 2 3 4' ⍝ Character matrix 'S1 1 64' ⍝ String 'G0 1 3 I4 1 3 E8 2 3 4 C1 1 32' ⍝ Nested array Basic text slide

  5. Associated Processor 15 – Restrictions Processor 15 creates a copy of the entire array in the workspace each time the array is accessed if: • The array contains any data other than C1, C4, I4, E8, or J16 • The array is nested Processor 15 only supports fixed size arrays Basic text slide

  6. Let’s try some things,,, Basic text slide
