8.1. Text Data Format Parsing

8.1.1. DCF

DCF is the object binary data format provided as standard by AROAPL.

encoding:

⎕IMPORT ← "FS";
⎕IMPORT ← "DFP";

PATH ← "path/to/data.dcf";

DATA ← ⟨"SAMPLE", ⊤, 4 5 ρ ⎕RAND, ⟨"SOME"⟩ ⟨"OPTIONS"⟩⟩;

⎕FCREATE ← PATH;
⎕FPUTB ← ⟨PATH, ⎕DCFE DATA⟩;

path/to/data.dcf

...

decoding:

⎕IMPORT ← "FS";
⎕IMPORT ← "DFP";

PATH ← "path/to/data.dcf";

DATA: ⟨κ[?], β, φ[? ?], ⟨κ[?]⟩[?]⟩ ← ⎕DCF ⎕FGETB PATH;
⎕ ← DATA;
