sprintf( "%s%$Fmt%s", ("%$Fmt=|", $TestStr, "|"))
This is in Perl for Dummies, 4th ed, p160.
I'm trying to understand this ...
the first part, "%s%$Fmt%s", my understanding is the format part,
which specifies the formats for the second part, thelist part, ("%
$Fmt=|", $TestStr, "|"): %s for "%$Fmt=|", %$Fmt for $TestStr, and %s
for "|", respectively. Is this correct?
Then what is %$Fmt, it seems a % for format and then a variable $Fmt,
the book did not mention any format string like this ...
Anyone can shed some light? Thanks!
