.SH EXAMPLES
+.PP
A simple conditional:
+.PP
.CS
\fBif\fR {$vbl == 1} { puts "vbl is one" }
.CE
.PP
With an \fBelse\fR-clause:
+.PP
.CS
\fBif\fR {$vbl == 1} {
- puts "vbl is one"
+ puts "vbl is one"
} \fBelse\fR {
- puts "vbl is not one"
+ puts "vbl is not one"
}
.CE
.PP
With an \fBelseif\fR-clause too:
+.PP
.CS
\fBif\fR {$vbl == 1} {
- puts "vbl is one"
+ puts "vbl is one"
} \fBelseif\fR {$vbl == 2} {
- puts "vbl is two"
+ puts "vbl is two"
} \fBelse\fR {
- puts "vbl is not one or two"
+ puts "vbl is not one or two"
}
.CE
.PP
Remember, expressions can be multi-line, but in that case it can be a
good idea to use the optional \fBthen\fR keyword for clarity:
+.PP
.CS
\fBif\fR {
- $vbl == 1 || $vbl == 2 || $vbl == 3
+ $vbl == 1
+ || $vbl == 2
+ || $vbl == 3
} \fBthen\fR {
- puts "vbl is one, two or three"
+ puts "vbl is one, two or three"
}
