your code does the following first it defines a word called variable (bad choice, since variable is already in use, nevertheless possible). Unless you have a word buffer already defined, the definition will fail with exception -13. If there is a word buffer defined, the definition will compile and when calling the new variable word it will call you buffer word and allocates 1024 bytes of RAM. Since you do not keep the address of this area (HERE is your friend), the memory is essentially blocked but cannot be accessed. what you probably intended to do is 1024 buffer: foo It allocates 1024 bytes of RAM and creates a word foo which when called leaves the start address of the RAM region. Using buffer: inside a colon definitions is possible, but advanced dark art ;) HTH Matthias _______________________________________________ Amforth-devel mailing list for http://amforth.sf.net/ Amforth-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/amforth-devel
