AudioED: Pointers - June 18, 2025

Pointers...

 

I first learned of Pointers

in 1982, CS113...

 

I had to write a Streaming Text Editor

in Jenson & Wirth Mainframe Pascal.

 

I looked at my Textbook, and found

a data structure called a

LINKED LIST.

 

I wrote my Editor using LINKED LISTS

and Pointers, on Hollerith Cards.

 

The Computer Lab assistants couldn't help me when it failed to compile.

 

LINKED LISTS was a second semester topic...

 

They knew nothing about it.

 

Finally, an advanced Grad Student

looked at my code...

 

There was no problem with it.

 

The only reason it failed to compile,

was because the Mainframe was not

allocating enough memory for

my task.

 

A simple memory allocation

card change allowed it to compile.

 

It ran correctly.

 

This was 1982, before somebody

invented the World Wide Web...

In 1989...

Seven years later.

 

The WWW uses POINTERS...

 

Oh, and one more thing ...

 

The Air Force used our Mainframe ...

The Web was invented by English computer scientist Tim Berners-Lee while at CERN in 1989 and opened to the public in 1993. It was conceived as a "universal linked information system". Documents and other media content are made available to the network through web servers and can be accessed by programs such as web browsers. Servers and resources on the World Wide Web are identified and located through character strings called uniform resource locators (URLs). -wiki
