Useful Routines For ZBASIC

By Dave Kelly, MacTutor Editorial Board

Hello! Are any of you tired of switching back and forth between versions of Basic? Although ZBasic still holds an edge over other Basics in the competition, there are benefits in favor of using other Basics from time to time. The frustrating thing about it is when you try to use a command, syntax, or subroutine with the wrong version of Basic. It’s easy to do if you switch back and forth very often. It’s also frustrating when your favorite function isn’t implemented the same (or not at all) from what you are used to.

Charles Stricklin has sent in three functions which he wished were already implemented in ZBasic. These have been designed to add to your ZBasic library of routines. The GETINDSTRING$ function works similarly to the GETINDRESOURCE function in the Macintosh toolbox. This routine allows easy retrieval of strings stored in a ‘STR#’ resource.

The GETRESWINDOW and GETRESMENU functions will get WIND and MENU resource data and interpret the resource to open up windows and setup menus using standard ZBasic statements. This is useful if you would like to use resources like ‘real’ applications do.

The program demonstrates the use of these functions. In developing this and through debugging the functions I am now even more aware of the missing capability to include resources from a resource file when compiling with ZBasic. This is a deficiency which I would hope Zedcor has as #1 on their ‘TO DO’ list. Charles also listed this problem as high priority and wrote a short routine as a work around for the meantime:

debugging = -1: ‘(or TRUE if defined previously)TRUE during development.

“OpenResourceFork” :’used in development only
 LONG IF debugging :’we’re still writing this
 CALL PARAMTEXT(“Do you want to use a specific resource”,”file?”,””,””)
 myAnswer = FN CAUTIONALERT(3,NIL) :’gets my answer from alert
 LONG IF myAnswer =1 :’I said “YES”
 resourceFilename$ = FILES$(1,”rsrc”,,volume)      :’gets a filename 

 ‘(created with ResEdit)
 refNum = FN OPENRESFILE(resourceFileName$)  :’and opens it’s  
 ‘resource fork
 END IF :’(myAnswer = 1)
END IF  :’(debugging)
RETURN :’(“OpenResourceFork”)

Other items on the ZBasic “Wish List” include:

(to be fixed):

• The “Save Changes?” alert should only be called after the user has actually made changes to an existing document... especially not right after launching ZBasic itself when opening an existing document.

• ZBasic doesn’t run reliably under MultiFinder. After several passes editing and running, ZBasic aborts even with 2.5+ Meg memory allocated to ZBasic. I’ve never had this happen when not running Multifinder. I suggest that Multifinder be turned off when editing and debugging ZBasic programs.

(to be improved):

• The ‘Find’ command is somewhat useless without a ‘Change’ command.

• The editor, even with the vast improvements over earlier versions, is still clumsy in several (many) areas.

• The default tab settings are a nuisance. This should be user definable.

• Editing would be much easier if more than one edit window (different files too) could be open at the same time.

• Lower the price. The ToolBox Editor should have been part of the package to begin with. The Program Generator is useful if you don’t already have your own custom BASIC shell defined.

On the plus side, ZBasic is still the fastest and has been very reliable since version 5.0 was released. If the price were still under $100, it would be a bargain. At the present time LightSpeed Pascal or C is a much better bargain when compared with ZBasic.

I’m sure that there are others routines which MacTutor readers have been using which would be useful to others. Send your routines to me via MacTutor and see your name in print! Thanks Charles!
