2 * FML interpreter. Europagate, 1995
5 * Revision 1.5 1995/02/09 14:37:19 adam
6 * Removed .depend from cvs. Removed function fml_mk_list.
8 * Revision 1.4 1995/02/09 14:33:37 adam
9 * Split source fml.c and define relevant build-in functions in separate
10 * files. New operators mult, div, not, llen implemented.
12 * Revision 1.3 1995/02/09 13:07:15 adam
13 * Nodes are freed now. Many bugs fixed.
15 * Revision 1.2 1995/02/07 16:09:23 adam
16 * The \ character is no longer INCLUDED when terminating a token.
17 * Major changes in tokenization routines. Bug fixes in expressions
18 * with lists (fml_sub0).
20 * Revision 1.1.1.1 1995/02/06 13:48:10 adam
21 * First version of the FML interpreter. It's slow and memory isn't
22 * freed properly. In particular, the FML nodes aren't released yet.
