QDCALC

QDCalc is a survey calculation tool, initiated as a project many years ago.  Although it is primarily written in an old version of Borland Turbo Pascal (v. 3.01), do NOT be fooled - QDC is a professional tool and is the product of

• over 21,000 lines of compiled Pascal code
• over 3500 lines of assembly code (and I wrote the assembler!)
• many, many sweaty hours of programming and debugging!

QDC was not developed to replace your existing calculation software, but to supplement it. It can co-exist with other, more comprehensive packages, and share data through ASCII text files. While QDC may never really be considered a finished product(?), I heartily encourage you to try it. Debugging is extensive and I believe QDC is powerful and safe. Features of QDC are too numerous to cover here, but a brief overview of features would include:

• thoroughly used and tested in MSDOS, Windows 3.1, Windows 98, Windows NT 4.0 and Windows XP Pro. Operates in full screen mode or in a window.
• capacity of over 10,000 2-D or 3-D (mixed) points
• VERY fast (instant!) point access and handling
• random point numbers from 1 to 65535, including optional lettered prefixes (eg. A1, T25)
• pre-assigned (by user) point descriptions for any point
• easily manipulate single points, or groups of points using point sets
• logical data entry using +, -, *, / or parentheses (eg. distance = 2*15-0.02), and more
• context sensitive pop-up help screens
• extensive configuration
• Network Aware feature for data protection with multiple users
• limited printing of routines, to real printer or to file
• printing of co-ordinate data to real printer or to file
• detailed searchable User's Reference (Windows-based .CHM file)
• pop-up HP style (stack oriented) calculator. Calculator is programmable!
• use calculator contents in any data input
• POWERFUL macro feature; create problem solving macros, solve ANY area or positioning problem. Macros can be memorized on the fly, or pre-written in text files.
• read or write ascii data files (pt#, north, east, elevation, description) in a variety of formats
• automatically generate DXF output, as you calculate, or send points and data out as DXF manually
• curve solver - solve any curve from any available information about it
• all traversing, inversing, transformation (scale, shift, rotate) functions
• all intersections easily done, with offset options!
• user configurable azimuth format, decimals, sound, window placement, etc.

For raw calculation power and user flexibility, I stack QDC against any and all comers!

With the advent of Windows®, QDCalc has been upgraded to take advantage of some of the features of Windows®, such as easy install/uninstall, and hypertext linked help.  Have a look at the User's Reference, or download and install QDCalc to use it!

QDCalc need not (and probably can't ) replace your existing calculation program, but can easily supplement it's performance.  QDCalc's macro facility is the most powerful problem solver around.  Give it a try!

DOWNLOAD QDCalc

Current version: 1.03.2 (June, 2005)

Note: the DOS version does NOT contain the detailed User's Reference (pop-up help only).  If the DOS version is used, the user must:

• extract the necessary files to a suitable directory
• create any batch files, etc. manually to run QDC.COM.  QDC could require 2 parameters (eg. QDC %1 %2) if used in a batch file.
