+"tag tec mode,fmt",
+where
+-      tag is the field number used in the index posting
+-      tec is the indexing technique (see below)
+-      mode is a Mmc formatting mode or, for tec 5..8, a prefixing format
+-      fmt is some format expression, typically a single field like v24
+
+
+*      formatting modes
+indicated by Mmc, where m is a character indicating some translations,
+and c is a character indicating the handling of case; default MPL
+
+m
+-      P proof mode: no changes applied
+-      H heading mode: angle brackets are removed,
+       ^x is replaced as ';' for x=a, ',' for x=b..i, '.' for others
+-      D data mode: like heading mode plus '.  ' after each field
+
+c
+-      L lower case: no changes applied
+-      U upper case: (ASCII-)characters are converted to "uppercase" as listed
+       in the file ISISUC.TAB (a textfile containing 256 replacement byte values
+       like ... '096 065 066' ... in 16 lines of 16 numbers each)
+
+
+*      indexing techniques
+-      0 one entry per line (format should produce appropriate newlines with /)
+-      1 one entry per line or subfield (use proof mode MPx to retain ^x)
+-      2 one entry per each term in <angle brackets> (use proof mode)
+-      3 one entry per each term /between slashes/
+-      4 one term per "word":
+       a word is a sequence of 'alphabetical characters' as listed in the file
+       ISISAC.TAB (a textfile containing numbers like ... '098 099 100 101' ...).
+       "stopwords" (listed in the db's .stw-file) are ignored
+-      5..8 like 1..4, but instead of applying a mode Mmc,
+       every entry with delimiter 'd' is given a prefix 'p' like
+       1 8 '/TI=/',v24 (prefix //-entries with TI=)
