00100 COMMENT * SIMULA specification;
00200 OPTIONS(/E:CODE,filcopy);
00300 INTEGER PROCEDURE filcopy(source,dest);
00400 REF(Infile)source; TEXT dest;
00500 COMMENT Copies source to dest block by block.
00600 Works only with disk files. Unlike ordinary SIMULA I/O, creation
00700 date will be preserved, also any version number (.RBVER).
00800 Direct buffer-to-buffer copy, no intermediary Image.
00900 Result is -1 if copying succeded, otherwise zero (or 2 if some file
01000 is not on disk).
