* newheader(t,fp) start new information header identified by string t |
10 |
– |
* isheadid(s) returns true if s is a header id line |
10 |
|
* headidval(r,s) copy header identifier value in s to r |
11 |
< |
* dateval(t,s) get capture date value |
12 |
< |
* isdate(s) returns true if s is a date line |
13 |
