%n term:

Sample (%n term is in red): %1<%+12.3f(E1-10)>

%n is one of the standard Search and Replace Regular Expression replacement terms - %1, %2, %3, and so on. This must be present and must be immediately before the first opening < character. When this is so the formatting specifications you supply will be applied to that %n term. See %n terms for more information.

Examples:

%1<%06ld>: Take the %1 material and output as an integer number, 6 places wide, 0 padded to the left.

%9<%06ld>: Same thing but to the %9 material.

You can have multiple terms in the overall replacement string. For example, this is OK:

S:+[0-9.\-\+]+[ \t]+[0-9.\-\+] ?? ??? +[0-9.\-\+]

R:%1<%06ld> and %3<%06ld> and %9<%06ld>
