Mark,
I don't think I can use the block form, or am I confused? Maybe if I
change the form slightly I can do it. But the values of the variable do
change
eval("\$ret=\$data\=\~$filter");
I suppose I could strip the slashes and any modifiers from $filter and
rewrite it thus: eval{"\$ret=\$data\=\~/\$filter/\$mods"}
I understand this may be faster, but it's not clear from my
documentation what it would do differently. Is that what you had in mind?
And- how can I trap the warning? In this case it's coming from an embedded
$ in my string (which I can look for), but I'm concerned about other
warnings that I might not anticipat:-) Thanks again for the help!
