This is an internal function used by
formats, though you may call it,
too. It formats (see perlform) a list of values according to the
contents of PICTURE, placing the output into the format output
Eventually, when a
write is done, the contents of
are written to some filehandle. You could also read
and then set
. Note that a format typically
formline per line of form, but the
formline function itself
doesn't care how many newlines are embedded in the PICTURE. This means
tokens will treat the entire PICTURE as a single line.
You may therefore need to use multiple formlines to implement a single
record format, just like the format compiler.
