.H 2 "findstring"
The findstring function is used to match a fixed string against a set
of strings.
This function takes at least one argument.
The first argument is the fixed string,
the second and subsequent arguments are matched against the first.
The result contains one word for each of the second and subsequent arguments,
each will either be the empty string (false) or the string to be matched,
if a match was found.
.H 3 Example
.TS
center,tab(;);
l l.
Expression;Result
_
[findstring a a b c];a "" ""
[findstring a b c];"" ""
.TE
Quotes are for clarity,
to emphasize the empty strings.
Because the empty string is "false",
this can be used in an
.I if
statement:
.eB
if [findstring fish [sources]] then
sources = [sources] hook.c;
