tctmttest write [ -tl ] [ -td | -tb | -tt | -tx ] [ -rc num ] [ -lc num ] [ -nc num ] [ -xm num ] [ -df num ] [ -ip ] [ -is ] [ -in ] [ -it ] [ -if ] [ -ix ] [ -nl | -nb ] [ -rnd ] path tnum rnum [ bnum [ apow [ fpow ]]]

Store records with columns "str", "num", "type", and "flag".

tctmttest read [ -rc num ] [ -lc num ] [ -nc num ] [ -xm num ] [ -df num ] [ -nl | -nb ] [ -rnd ] path tnum

Retrieve all records of the database above.

tctmttest remove [ -rc num ] [ -lc num ] [ -nc num ] [ -xm num ] [ -df num ] [ -nl | -nb ] [ -rnd ] path tnum
