15.5.257 fstring

fstring(format, argument1 [, argument2 …, /skip_undefined])

Transforms the arguments to an ascii string under guidance of c-format string format. The arguments are modified to suit the data types expected according to the format. If keyword /skip_undefined is specified, then undefined arguments (and the format entries corresponding to them) are skipped. This is useful if the number of arguments to fstring is not known exactly in advance.

Alias: sprintf
