We have some links on our site to resources that you might find useful
[url]www.kednos.com[/url] PL/I's block structure with lexical scoping and
ON-conditions
would make an interesting topic, and might lead people to the realization
the C and C++ are pedestrian at best.

There's a fairly good bibliography at

Lots of the articles, especially the ACM stuff, should be available online.

To give you a hint, PL/I allows GOTO using LABEL variables between
procedures. Somewhat similar to C's setjmp/longjmp, one can pass a
LABEL variable to another routine.

Another interesting language feature is the range of data conversions
PL/I allows. Conversions between character and numeric types are done
when needed, consider:

DCL (X,Y) CHAR(20);
X='1234';
Y=SQRT(X);
PUT LIST(X,Y);

try IBM manual pages:

<shamelessplug>
if you need to expirement with just the syntax of pl1, try to visit
pl1gcc.sourceforge.net

There was a paper written in the 80's (I think) titile something like
Return of PL/I King of programming languages, anybody have a reference to
it

In summary of your programming languages paper you shud mention that PL/I is
NOT a viable language
as below link indicates (no usage/development whatsoever)

vs one of the most active development languages

It was called "Has the King returned?".

So, Robin, do you have a link for it?
