File_type:
Example
TYPE
person = RECORD
name: PACKED ARRAY [1..30] OF char;
age: 1..100;
END;
person_file = FILE OF person;
bit_vector = PACKED ARRAY [1..100] OF Boolean;
vector_file = FILE OF bit_vector;
data_file = FILE OF integer;
doc_file = text;
Standard Textfiles
text
Text type variables are called textfiles . The standard file type text
permits ordinary input and output that is oriented to characters and
lines. Text type files have two important features:
* The components are type char .
* The file is subdivided into lines by special end-of-line markers .
Textfiles cannot be opened for direct access with the procedure open .
Textfiles can be sequentially accessed, however, with the procedures
reset, rewrite, or append . All standard procedures that are legal for
sequentially-accessed files are also legal for textfiles.
Certain standard procedures and functions, on the other hand, are only
legal for textfiles. These procedures are:
* eoln
* linepos
* overprint
* page
* prompt
* readln
* writeln
Textfiles permit conversion from the internal form of certain types to an
ASCII character representation and vice versa.
Example
VAR
myfile: text;
i: integer;
r: real;
