Wow. Another one just as I posted above...

I have been deleting on average about 100 spammer registrations per day. Just now I deleted another 172 that appeared within the past few days. When I got done, there was already three more. What's going on with the internet? Is there a plot to use AI and spambots to render traditional forums unreli...

Update! I was about ready to send this project to the graveyard as I have been working on newer things. With the newer Express Calculator and RP1 projects being written in C and PHP, I thought it would be good to update RPN Calc so there's an example of my expression evaluator in Quick BASIC/QBasic....

50 views so far. not bad. it will grow.
listened to it at work the other day.
a solid track. make 3 and release a demo!

I realized there's no update thread. Until now, it has been worked on mostly in silence. Most efforts have been put into Express BASIC lately, but I am still dedicated to updating Net Basic. While working on Express BASIC, I found an issue with handling of negation. After fixing the issue, I have be...

Express Calculator A command line scientific calculator for DOS, Windows, and Linux. Written in C. Operator precedence: NOT(), ^, MOD, *, /, +, -, <, >, <=, >=, =, <>, XOR, AND, OR Functions: ABS() INT() SQR() SIN() COS() TAN() ATN() LOG() ROUND() SGN() EXP() PRIME() FACTORIAL() RND PI Set the accur...

This week brings a big update. Handling of negation has been improved. For example, -(10 +1) returns -11 as it should. As opposed to -9. I had never accounted for negating outside of parenthesis. Only in front of a variable or literal value. The solution for now is to swap the - with a _1* and later...

Long awaited update!

Handling of negation has been improved.
Operations display is now complete and optional.
Hexidecimal notation and evaluation is now supported.
The # symbol inserts the last evaluation in an expression.
User interface has been improved.
Backend errors are fixed.

Here's a simple demo of sending output to the parallel port in DOS. The output is viewable with a rs232 quick tester like this:

Hexidecimal values may now be denoted in expressions using the &H prefix. The INP() function and OUT command has been added to the DOS Edition. It makes sense to allow DOS programmers the ability to access ports. This only works on the DOS .Edition and not DPMI, Win32, or Linux. While this allow...
