<p><b>New page</b></p><div>Here's a quick recap:<br />
<br />
1965, [[DonNelson]] writes English in what noted historian<br />
[[HenryEggers]] refers to as "Flowchart Notation Language",<br />
with each instruction being represented by a box. This<br />
predates the assembler.<br />
<br />
1968, [[DickPick]] takes the code to a Sigma 7 machine at <br />
the University of California, Irvine.<br />
<br />
1968-70 The Editor arrives. It is pitched as the update<br />
mechanism. Customers don't buy into that, so "Batch" is<br />
born. (Think B[[/ADD]] here.) Curiously, Batch was an attempt<br />
at implementing the Update Language portion of Nelson's<br />
original flowcharts. While it never reached completion<br />
in Nelson's lifetime, Dick Pick completed it around 1990<br />
in what he called the "Update Processor". (Another story<br />
in and of itself). Also in this time block is when the<br />
Pick assembler arrives. Both the Editor and assembler <br />
were written by Chandru Murthi.<br />
<br />
Around the same time, PROC shows up. Everyone was used<br />
to JCL, and this was simply the Pick JCL language.<br />
It is believed that Chandru wrote this as well.<br />
<br />
1973-74 The assembler debugger arrives, written by [[KenSimms]].<br />
Chandru observes that it was an impressive piece<br />
of work, given that he didn't have a debugger to work with.<br />
<br />
Circa 1973-1974 Will Olsen writes the "Infact User Modes",<br />
adding user-exits to PROC to facilitate file update.<br />
One of Olsen's early clients was the CIA. The Infact <br />
User-Modes became part of the basic Pick distribution.<br />
<br />
1974-75 BASIC arrives, written by [[KenSimms]]. The Pick version<br />
of this is called "SBASIC" (Ken's initial). The Microdata<br />
version is called "EBASIC", cleverly named by Tom Ells at<br />
Microdata.<br />
<br />
Circa 75-? John Timmons and Paul Desjardine produce "PORC".<br />
(spelling double-checked on that). PORC was based on PROC,<br />
with each of Olsen's user-exits replaced with an instruction.<br />
PORC becomes the starting point for RPL, headed up by Tim<br />
Holland while under the employ of SMI in Chicago.<br />
