MAWK fatal error: "return outside function body"

[calabrra]

Greetings,

I'm running the ported mawk version 1.3.3 under Win 2K Pro, and am getting the fatal error message:

"(Source) Line nnn: Return outside function body."

for all functions with a "return" statement. Strangely, I don't get any errors when interpreting the exact same code with awk95.exe and gawk.exe.

Can you determine what is wrong?

Thanks,

Sample code:

###################################################
func qword_to_double (qword, mantissa, exponent) {
###################################################

ifunc++;

#Convert a quadruple hex word (64 bit) value to double
#precision IEEE floating point.

#First, convert to binary
qwordbin = hex2bin(qword);

#Extract sign bit
sgn = substr(dwordbin, 1, 1) == "1" ? -1 : 1;

#Extract exponent
exponent = bin2uint( substr(qwordbin, 2, 11) );

#Extract mantissa
mantissa = bin2uint( substr(qwordbin, 13, 52) ) / 2^52;

#print "Hex to Double:\t", qword "\s", qwordbin "\s", length(qwordbin) "\s", sgn "\s", expbin "\s", mantbin "\s", exponent "\s", mantissa "\n" > "DPDiag.txt";

#Put it all together and return ...
return (sgn * 2^(exponent - 1023) * (1.0 + mantissa) );

}

I found the solution thanks to Mike Brennan:

Change "func" to "function".
