If you know that oct2 will always be a string, and oct4 will always be an
slist, you can try something like this completely untested snippet. Basically,
make a new list which starts with a discardable space character. Then join the
elements with a comma followed by the desired prefix, and then split that back
up on just the comma - leaving the prefix on all but the first element.
Finally grep the dummy space back out of the freshly split list.
any::
"separator" string => ",";
"prefix" string => "10.$(oct2).20";
"temp_namelist" slist => { " ", @(oct4) };
"nameserv" slist => grep (
"^[^\s]+$",
splitstring (
join("$(separator)$(prefix)", "temp_namelist"),
"$(separator)",
"99999999999"
)
);
