Page

The standard procedure page advances the output of a given textfile by one page. Page could refer to a piece of paper if the destination is a physical printer, or could imply blanking the entire screen, the specific behavior is implementation-defined.

signature

Page takes one text file as a parameter. It determines the destination. If the destination is output, it can be omitted. page; is short for page(output);.

behavior

Provided the destination is open for writing:

1. If not at the beginning of a line, do a writeLn(destination).
2. Implementation-defined method of advancing to the next “page”.

implementation

• On IBM mainframes, advancing to the next page was achieved by putting a 1, that is the character of the digit 1, in the first column of a line.
• On most machines using ASCII though, it simply means emitting a form feed character, i. e. chr(12). The FPC and the GNU Pascal Compiler use this method.

notes

• In the FPC page is only available in {$mode ISO} and {$mode extendedPascal}.
• Page is a regular identifier and as such can be redefined.
