If yes, then use mecej4's suggestion of passing the values by argument or by buffer reference. If no, then look in MSDN as to how to: Thanks for your replies.

But the two programs can not be combined. I am using exactly same method described in MSDN for pipe mechanism to connect two programs.

R for Windows FAQ

Are does meaning less signs the binary form of the number? Steve, I have no experience in using Hex format. I just did a quick search and found out it is very complicated and actually needs to save some charachters for: The point of converting to binary form was to reduce the size of data and make the write and read process faster.

But this Hex format seems to take more size than even sending actual number! Since I want to transfer very large number of data double percision numbers I am looking for simplest and fastet way.

Can you please help me. I am not sure what you are seeing. The strange characters are due to the console trying to interpret the floating point binary data as if they were text characters. You can, if you want, use a normal decimal format such as E or F to convert the floating point value to decimal characters, and then an f format in fscanf in C to "read" it, but you'll be converting from binary to decimal back to binary and this conversion is usually not exact, since many binary floating values don't have exact representations in decimal.

This is why I suggested hex format - you won't lose any bits in double-conversion.

I very much doubt sending 18 characters vs. If you are willing to give up on trying to display values to the console you can use your original approach, however. Just don't expect to be able to "print" the value as it is sent. This is the simplest and fastest possible block transfer, with absolutely zero in the way of formatting or any data transformations.

WriteFile is very direct from IVF, and contains everything you want:Dec 31,  · I have a similar need to write to an output file with ascii id and binary data: Sample output file: Input one (in ascii) Input two (in ascii) I have to use fortran 77 on a VAX system.

So I guess I can’t use FORM=’BINARY’ as suggestion. This page briefly describes every file format (or actually the file name extensions for the formats) that we have been able to learn about.

This program was designed to convert scientific data in a quick and easy way (so you can view them in Excel for instance), it's in no way meant to replace a program reading directly the binary files which will always be much faster. Your Help Needed If you know Fortran, please write code for some of the tasks not implemented in Fortran.
