Rutgers University Algol 68 Interpreter - runs under WIndows, Linux and DOS

Not all the exotic features are implemented. In particular there are no semaphores, formats and parallel-clauses.
Long and short modes are not implemented and will cause errors to be reported if used.
The stadard prelude has a number of ommissions, particularly transput which is restricted to standard input and output only.
Transput event routines are also not supported.

Lexical style

Rutgers ALGOL 68 is case-sensitive and uses quote-stropping. The standard bold-words are in lower case, e.g.: <lang algol68>'begin'

   print( ( "Hello, World!", newline ) )

'end'</lang>

Building and running under Windows

To build under Windows, download the Linux version and unpack to a suitable directory (e.g. \algol\RutgersAlgol68 is assumed here). Place the following batch file into the the directory and execute it. The batch file asumes TCC is being used as the C compiler, change as appropriate. The DEFINES and ALINC variables may also need to be changed.

<lang dos>rem build.bat: build the Linux version of RutgersAlgol68 under Windows

rem set CC and DEFINES as appropriate for your C compiler rem if your compiler does not come with include/sys/times.h, set ALINC=-I..\.. to include the dummy times.h rem if your compiler does have a include/sys/times/.h, set ALINC= rem the following are for tcc ( tested with version 0.9.26 (i386 Win32) )
