Extentions to BASIC

Here I will introduce you to a number of new BASIC statementsthat add power to that language, and will hopefully make programmingeasier for those of you who are used to discussing subjects on Usenet.The first new statement we will address today is the BEFORE statement.The BEFORE statement makes it easier for the programmer to correct a mistakewithout changing the structure of the program.Here is an example:10 PRINT "ARE THE GREATEST"20 END50 BEFORE 1060 PRINT "WE AT HILLVIEW"70 ANYWAYS80 PRINT "OUR SOFTWARE IS 100% BUG FREE"When run, this code produces the following output:WE AT HILLVIEWARE THE GREATESTOUR SOFTWARE IS 100% BUG FREEThe ANYWAYS statement introduced above, terminates a BEFORE, BEFOREstatement are also terminated by a BTWWW (BackToWhereWeWhere) statement.BTWWW and ANYWAYS have the same function, so10 PRINT "ARE THE GREATEST"20 END50 BEFORE 1060 PRINT "WE AT HILLVIEW"70 BTWWW80 PRINT "OUR SOFTWARE IS 100 % BUG FREE" produces the same output as the first example:WE AT HILLVIEW ARE THE GREATESTOUR SOFTWARE IS 100 % BUG FREEThe next new statement I want to introduce you to, is the AFTER statement.The AFTER statement makes it easier to execute things later, here and example ofit's use:10 PRINT "BASIC NEEDS TO BE EXTENDED WITH MORE USEFUL COMMANDS"20 AFTER 10030 PRINT "BECAUSE I SAY SO"40 ANYWAYS50 PRINT "TO MAKE PROGRAMMING EASIER FOR COMMON PEOPLE AND ENGINEERS"100 PRINT110 PRINT "AND IT IS SIMPLE"This shall produce the following output:BASIC NEEDS TO BE EXTENDED WITH MORE USEFUL COMMANDSTO MAKE PROGRAMMING EASIER FOR COMMON PEOPLE AND ENGINEERSBECAUSE I SAY SOAND IT IS SIMPLEThe ANYWAYS statement is here again used to terminate an AFTER directive.The last statement I will introduce you to today is the NEVER statement.Here and example of the use of NEVER:10 PRINT "OUR SOFTWARE IS THE BEST20 PRINT "IS HAS SOME MINOR BUGS, BUT WE ARE WORKING VERY HARD TO FIX THESE"30 PRINT "THIS ENDS OUR LESSON FOR TODAY"40 NEVER 2050 AFTER 2060...

Microsoft .net libraries in an OS kernel? I don't think so.

I posted that just to hear s/w people scream.

It used to be COBOL tossed out as an OS language that was used to make s/w engineers scream.

Hmm, certainly the facility in COBOL to create self-modifying code could be used to create a really disgusting mess full of holes... Is it really sure Microsoft doesn't use COBOL? Well, I guess buffer overflows in C works well enough.
