Vintage BASIC
(ver 1.0.2)
Freeware


Vintage BASIC is a Windows script interpreter that runs 
"line-number" BASIC (*.BAS) scripts from the Command Line
(such as those intended to be run with DOS GW-BASIC).  It 
is -NOT- compatible with either the QuickBasic (Qbasic) 
or Visual Basic scripts.

QB64 [SDL]
(ver 0.954)
Abandoned Freeware


As a courtesy for persons confused about the inability to 
run some *.BAS files in Vintage BASIC, here is QB64.

Although they also had a *.BAS extension, files written for 
Qbasic were very different from traditional BASIC scripts.  
For these scripts, you will need to run this QB64 compiler.  
QB64 is a Qbasic compatible compiler that creates working 
Windows Executable (*.exe) files from Qbasic *.BAS files.   
QB64 does -not- recognize Visual Basic (*.VB) files.  

Note that Qbasic (which QB64 emulates) was not fully backwards 
compatible with "line-number" BASIC programs intended for the 
GW-BASIC interpreter (use Vintage BASIC for these).  

QB64 also extends the QuickBasic language with new keywords 
and some new features, such as playing music or sound files 
and using 32 bit graphic file images. TCP/IP communication 
is also available. 


NOTE: QB64 [SDL] has been abandoned.  A new implementation, 
QB65 [GL], is now in production, but it will only work on 
Windows XP and above.
