The following macros implement an easily-definable (and therefore
easily modifiable) set of translate tables for the DN60 code.
There are three user-visible macros, namely CHAR which defines an
ASCII character (or its octal representation) as being equivalent to
some EBCDIC code (represented in hexadecimal); EBCTAB which generates
the resulting EBCDIC to ASCII translate table and ASCTAB which generates
the ASCII to EBCDIC table. All the rest of the macros below are internal
to one or other of these three. The following list shows the macro name,
who calls it, and what it does.
CHAR user defines E.xxx and A.yyy symbols to store character mapping;
also defines DExxx and DAyyy macros to hold descriptions of
the characters (only if FTTRLS is non-zero)
OCT CHAR converts the hexadecimal first argument of the CHAR macro into
octal (note there are two versions, one for MACDLX edit 667
or thereabouts and one for MACDLX 1031 and later)
OCT1 OCT (old MACDLX version only) converts each hexadecimal digit into
its octal equivalent
STOR CHAR creates a symbol E.xxx=yyy where xxx is the EBCDIC code
and yyy is the ASCII code; also creates A.yyy=xxx (for
the other translate table); if either symbol was already
defined, prints a warning that it was changing its value.
ASSGN CHAR used to do a symbol assignment where the source symbol has
to be made up of two parts concatenated together
DESTOR CHAR defines a macro DExxx to contain the comment line of information
about the EBCDIC character xxx (only if FTTRLS is non-zero)
DASTOR CHAR defines a macro DAyyy to contain the comment line of information
about the ASCII character yyy (only if FTTRLS is non-zero)
EBCTAB User generates the EBCDIC to ASCII table; if FTTRLS is non-zero
it prints the character-by-character description of the table
contained in the comment macros DExxx; if FTTRLS is zero, it
prints only .BYTE statements with the octal values. The table
is printed from 0-377, but stored in memory in such a way that
the first half is 200-377 and the second half (with the tag) is
0-177, thus permitting
MOVB char,Rx
MOVB EBCASC(Rx),Ry.
ESTOR EBCTAB used to generate the .BYTE v1,v2,v3,v4,v5,v6,v7,v8 line if
and FTTRLS is zero; it converts its entry symbols into others
ASCTAB with values of 0 if the entry symbol was undefined and
the entry symbol's value if the entry symbol was defined,
then calls ESTR1 to actually produce the .BYTE statement.
ESTR1 ESTOR counts up the number of characters in the values for the
.BYTE statement and generates one of three .BYTE statements
with the appropriate number of tabs to line up the comment
correctly. If FTTRLS is zero, forces the .BYTE statement
to print.
ECNT ESTR1 counts up the number of characters in all the value parameters
for the .BYTE statement
EBENT EBCTAB Generates the appropriate comment line if FTTRLS is non-zero;
if the current symbol is defined, it prints the value and the
description of the ASCII character it corresponds to.
If the current code is not defined, it prints that fact.
COMNT EBCTAB if FTTRLS is non-zero, generates a comment line to separate
groups of 16 descriptions (for readability).
CAT COMNT used to generate a concatenated comment line.
ASCTAB User similar to EBCTAB but generates ASCII to EBCDIC table;
since it is only 128. bytes long it has nothing funny about
its arrangement in memory (i.e. tag at beginning followed
by data).
ASENT similar to EBENT but for ASCII table (only if FTTRLS is
non-zero
HEXPR DESTOR, this is the start of the hexadecimal printing macro; it is
DASTOR, used only if FTTRLS is non-zero (because it is very expensive
and at assembly time) to cause the appropriate hexadecimal values
EBENT to be included on the comment lines printed for each entry in
the translate table. It merely sets a counter (N) to four, which
is the nesting level of the next macro (H2) and calls it.
H2 HEXPR this macro calls itself recursively, each time adding another
and argument (which is the next higher order hexadecimal digit
H2 of the number being converted) and pushing the previous ones
one place to the right. When it has reached its maximum nesting
level (N=0) it calls HX with the four arguments it has
produced. The caller of HEXPR must first define a suitable HX;
in our case DESTOR and DASTOR define a HX which merely defines
the DExxx or DAyyy macro (with the appropriate other information
already included). Note that there are two versions of
this macro also; the old MACDLX doesn't always process .MEXIT
correctly from deeply nested macros.
