- program t66_files;
- { t66 -- FILE types: `text' and `file of T'. CALC.PAS:144 is
- MCFile : file of CellRec; -- File to store sheets in
- A file variable is our own control block (FileVarSize = 4 bytes: the DOS
- handle and a mode word), because this runtime does unbuffered INT 21h I/O
- where TP3 keeps a 128-byte buffer inside the variable - a recorded
- divergence. `file of T' parses its element type for the RECORD size a
- Read/Write moves (here 2 bytes, an Integer); `text' is one byte per element.
- This increment is the TYPES and the variable layout only. The file
- operations - Assign, Reset, Rewrite, Close, EndOfFile, IoResult, and
- read/write with a leading file argument - are the next one, and are loud
- (unknown identifier) until then, not silently wrong. }
- var
- t : text;
- g : file of Integer;
- begin
- writeln ('files declared')
- end.
