• What is the difference between buying you product and registering?
  
  They mean the same thing. There is no difference between the two
   
• How secure is your ordering process?
  
  When you order our products we first collect some information like your name, PDA user name etc. After collecting this information you will be transferred automatically to a secure web site of a major American bank. It is a secure web site where you enter your credit card information. Ones the credit card transaction is completed the bank will redirected you back to our web site. Our in office local server will receive an email when the transaction was completed successfully, generate your registration code and email you the registration code automatically.
  
  Your credit card information will only be transfered via a secure web site directly to the bank not to us!

• What is my user name?
  
  There are several names for it but all mean the same. On the palm it is also called Hot Sync ID. Your user name can be found on the registration screen as shown below.

  
  
  
  

• I don't see the menu's on my palm?
  
  After starting our program just tap on me menu button under the applications button. This button is also circled in the screen shots above.
   
• Why does my registration code not work?
  
  The only reason for this is that either the user name we received does not match your current user name. Or the registration code was not entered correctly. The registration code is case sensitive. Enter characters capitalized when they are shown capitalized in the registration code.
   
• I lost my registration code. Can you email me my registration code?

• What is the differences between PDAcalc classic and CplxCalPro?
  
  • Testing and debugging scripts using PDAcalc classic is a lot easier. Pressing RUN to execute a script will transfer you automatically to the color-coded debug screen when an error is detected. This debug screen will show at which line the first error was detected.
     
  • Testing and debugging scripts using the windows version of PDAcalc classic is a lot easier then the palm version. After completing your script just press the hotsync button to transfer you script to your palm. No need to install the emulator or simulator on your desktop.
     
  • Selecting the angular unit in the preference screen will only affect the equations in the scratchpad. Before running a script the angular unit will always be set to degrees. We know that using degrees and complex numbers don't make much sense however there are more people using CplxCalPro and degrees than people who use CplxCalPro and complex numbers.
  • All values using the print functions will be printed including the zero. In CplxCalPro the function gprt(10,10,'Val=',val) will print all values for variable val except when val equal zero. Using PDAcalc classic the zero will also be printed. To ignore the last argument use a double single quote like gprt(10,10,'hello',''). The last argument is required since PDAcalc classic also checks for the number or arguments.
  • A reference to a user function must be between single quotes. int('f',0,4) will calculate the integral of user function f. The single quotes where not needed in CplxCalPro but is needed in PDAcalc classic.
  • The last two arguments of the gaxis() function where used to set spacing for labels on the x-axis and y-axis. PDAcalc classic uses auto scaling to find the right spacing for you. Set these last two arguments either 0 or 1 to ignore or draw the labeling.
  • The display format of the labeling of the axis in PDAcalc classic is also automatic which eliminates the use of the gxlbl() and gylbl() functions.
  • In PDAcalc classic an extra argument for the functions gpnt()  and gcir() was added. The first argument determents the color.
  • Use only a j or i behind a number to make it complex. Not before the number. Use 1j instead of just j. In CplxCalPro you could use just j to define a complex number but that could be very ambiguous since j is also commonly used by programmers as integer.
