with Signals the Start of a WITH Statement
with <rnames> do
<statement>;
Normally, if <rname> is the name of a record variable, then in order
to refer to a specific field in that record you must type
"<rname>.<fname>". However, if the record name <rname> is a long name,
or there are nested records, then referring to a field can get
cumbersome. The WITH statement allows you to drop the "<rname>."
prefix. For example, instead of saying
<rname>.<field1> := <rname>.<field2> + <rname>.<field3>;
you can say
with <rname> do
<field1> := <field2> + <field3>;
<rnames> One or more names of record variables, separated by
commas. Successive names can refer to fields of
previously named record variables.
<statement> Any legal statement. If multiple statements are
desired, use a compound statement.
