{printf ((FNR>1 && /^[0-9]/)?RS:"" ) $0} which runs for each line read from an input file calling the printf() function with a single argument that is the concatenation of two strings:
the record separator (RS, which defaults to the <newline> character) if the line number within the current in put file is greater than 1 (FNR>1) and (&&) the first character on that line is not a digit (/^[0-9]/); or the empty string ("") otherwise, and
the contents of the current input line without the trailing <newline> character($0), and
END {print""} which prints a <newline> character after the last line in the last given input file,
with one input file to be processed (myfile).
Since the 1st (and only) argument given to the printf() function in this code is a format string, this is a little bit dangerous. If any lines in your input file contain backslash (\) or percent-sign (%) characters, the printf() function interprets those characters in the format string argument as requests to perform formatting functions. The following might be a little bit safer:
which behaves like vgersh99's script except the format string argument now contains a %s format specifier to print a string argument, and the contents of the current line are given as a 2nd argument to printf().
