Formats list according to picture and accumulates the result into $^A.
Writes a formatted record to the specified file, using the format associated with that file.
Formats are defined as follows:
format [ name ] = formlist .
formlist pictures the lines, and contains the arguments that will give values to the fields in the lines. name defaults to STDOUT if omitted.
Picture fields are:
Left-adjusted field, repeat the < to denote the desired width
|@| | |...||Centered field|
|@#.##...||Numeric format with implied decimal point|
|@*||A multiline field|
Use ^ instead of @ for multiline block filling.
Use ~ at the beginning of a line to suppress unwanted empty lines.
Use ~~ at the beginning of a line to have this format line repeated until all fields are exhausted.
Set $- to zero to force a page break on the next write.
