PB is still very much in use and undergoing continuous development. Latest version is 9.02 Combined it with SQL Tools for ODBC connectivity and it rocks. To quote from http://www.powerbasic.com PowerBASIC 9 for Windows, our GUI compiler, creates applications and DLLs with the Windows look and feel. And PowerBASIC Forms, our Visual Dialog Designer, will have those GUI apps running in no time at all! For text mode, there's the PowerBASIC Console Compiler 5 -- no fluff, no animated puppets, just intense computing power. That's why it's said "We put the POWER in BASIC!". These new versions sport a number of exciting new features. Both compilers can create client COM applications using Dispatch, Direct, Automation, or Dual interfaces. PowerBASIC 9 For Windows can create COM components (servers) using Dispatch, Direct, Automation, or Dual interfaces. The inline assembler has been expanded to support the full range of SIMD opcodes. A complete graphics engine, a printer package for Windows GDI host printers, dynamic pointers, and thread local storage, to name just a few. Dynamic Dialog Tools has been expanded to support TreeViews, ListViews, ProgressBars, ToolBars, ImageLists, Tab controls, and much, much more. The built in graphics engine has been expanded to support keyboard and mouse input with easy to use statements. The built in GDI printer engine has been expanded. Select the paper tray, set the paper size, turn duplexing on and off, enable or disable collating, and more. Signed and unsigned bit variables, 1 to 31 bits wide, can be packed one after another in User-Types and Unions. We have FIELD string variables, and a FIELD statement for resizable data structures. Even THREADED variables for Thread Local Storage (data local to a thread). -- Stuart On 22 Oct 2009 at 15:31, Mark Breen wrote: > Hello Stuart, > Have not heard of PowerBasic since 2001, is is still in use? or is this an > old language that you still use through familiarity? > > Thanks > > Mark > > > 2009/10/20 Stuart McLachlan <stuart at lexacorp.com.pg> > > > 200 megabytes tirivial. > > > > I just knocked this up in PowerBasic (this is the complete program!): > > > > #COMPILE EXE > > #DIM ALL > > FUNCTION PBMAIN () AS LONG > > LOCAL strFile AS STRING > > LOCAL lngSTart AS LONG > > LOCAL strData AS STRING > > strFile = "ML_Data.mdb" > > lngStart = TIMER > > OPEN strFile FOR BINARY AS #1 > > GET$ #1, LOF(1), strData > > CLOSE #1 > > REPLACE "A" WITH "B" IN strData > > OPEN strfile & "fixed" FOR BINARY as#1 > > PUT$ #1, strData > > CLOSE #1 > > MSGBOX "It took " & STR$(TIMER - lngstart) & " seconds" > > END FUNCTION > > > > It compiles to an 11KB executable with no dependencies. > > > > It took 18 seconds to process ML_Data.mdb which is 774MB in size.
