When you have questions, first check the AD2.NG file. If the answer is not found there, check here before contacting Tech Support. This information applies to AD2 Toolkit (Vers. 2001 Rev D.).

Installation Warning!

 
Some users have had difficulty installing and we now advise turning off Anti-Virus and Personal Fire Wall software.

  Also, with Windows 2000, XP, and NT it may help to be logged in as an administrator.

How should I use the AD2 HyperText Manual?

  To read the manual from Windows XP, Me, 98, 95, 2000, NT or later, run WEG.EXE   (installed in the AD2 directory) and open the file AD2.NG. WEG  (Windows Expert Guide) can also be used to read your Zachary and  Clipper NG files, and others you may have received from other vendors.

  To read the manual from DOS when you’re not using Windows (or if using Windows 3.1), from the directory where you installed AD2, run:

      EHRT.EXE -L -P2

  This loads the manual as a TSR popup program, which you access by   pressing [Shift-F1]. (If you use Expert Help, copy ad2.ng and  zach_ref.ng to your Expert Help directory.)

How should I set up my working environment when using Win95/98/Me:
  In My Computer, Control Panel, System set the Hard Drive for Maximum Read Ahead Optimization.
  Set up an icon on your desktop for MS-DOS. Change properties to::
    Memory Tab: Initial Environment: 1024
                 EMS  4096
                 XMS  Auto
                 DPMI 8192
    Misc Tab: Fast Pasting (Not Checked)
Then use that icon to open a DOS Window, and that's where you'll do all your Zachary development.

Problem:  Linker Error: Unresolved externals.
  These represent linking in old versions of libraries or an old zac.ch file. Look in AD2.NG under AD2 Tips & Techniques, under the heading “Linker and Runtime Error Messages.”

Error: (b)ZTEMPVAR (0)  Unrecoverable error 650 Processor stack fault
 
This suggests you're not linking in the right AD2 or ZACH library, instead linking in an old version.

Linker Error: Undefined Symbol 'BLIMGRSTS'
 
ad_BlinkMode()--called by ad_SysTest()--in ad2 lib references a Blinker function.If you're not using Blinker, the easy way out is to add the following function somewhere in your program... it would be easiest in a procedure where you add it to the preprocessor directives in a U-field... that way it will be linked in for sure.

function ad_BlinkMode()  // Blinker bypass routine
return ""

MrEdit Routines

  Using the MrEdit routines: One user reported difficulty with the MrEdit routines, where the clipboard was not maintained properly, even to the point of an error when exiting the program. If you're using our MrEdit routines with MrEdit, be sure to compile our prg files with the following Clipper switches:

     -n -m -r

AD-Setup Wizard Compression

  The compression method was changed to provide faster compression and extraction, and to maintain file date stamps. If you prefer or need the earlier (ADC) system that can be switched on with an entry in the AD2.INI file. For details look in AD2.NG under AD Setup Wizard, File Manipulaton. Check the Compression paragraphs.
