The /:  command is used to delete input lines from the command history  so that they are not saved to a history file . This would be appropriate to remove input lines containing mistakes, etc., from the command history. The equations tex2html_wrap_inline34444 are parsed in the normal way before the value of the equation is determined.

The rounded value of each equation is intended to represent the integer address of an item retained in the command history . If this address does not match any entry in the current command history  then no action is taken. Otherwise, the effect is to remove from the command history  the input lines whose addresses are the rounded values of tex2html_wrap_inline34444 . (The addresses can be reviewed beforehand by issuing the !:  command.) If no arguments are given, then nothing happens. Whichever, this command line is not reproduced in the command history.
