17 : * Input/Output module
18 : * The IO module provides simple @sc{ascii-io} rendering options.
19 : * It is modeled after the tuple formats, but does not
20 : * attempt to outline the results. Instead, it is geared at speed,
21 : * which also means that some functionality regarding the built-in
22 : * types is duplicated from the atoms definitions.
23 : *
24 : * A functional limited form of formatted printf is also provided.
25 : * It accepts at most one variable.
26 : * A more complete approach is the tablet module.
27 : *
28 : * The commands to load and save a BAT from/to an ASCII dump
29 : * are efficient, but work only for binary tables.
30 : */

32 : /*
33 : * Printing
34 : * The print commands are implemented as single instruction rules,
35 : * because they need access to the calling context.
36 : * At a later stage we can look into the issues related to
37 : * parsing the format string as part of the initialization phase.
38 : * The old method in V4 essentially causes a lot of overhead
39 : * because you have to prepare for the worst (e.g. mismatch format
40 : * identifier and argument value)
41 : * Beware, the types of the objects to be printed should be
42 : * obtained from the stack, because the symbol table may actually
43 : * allow for any type to be assigned.
