I have an application that requires me to write normal string data or a number into a binary file. For example, if I have the string "ff", I want to write the byte FF to the output file. If I have the number 1, I want to write the byte 01 to the output file.
I have been using the pack function with either "c","C",or "H2" templates. I figured out early on that "c" is expecting a number and "H2" is expecting two valid hexadecimal digits (0-9,a-f). My question is this: what is the difference between "c" and "C"? I know what perldoc says - one is a signed char and the other is an unsigned char. So if I have the value 230, shouldn't that be illegal for a signed 8-bit number, since the valid range is -127 to 128. I tried every value between 0 and 255 and there is no difference between "c" and "C". Also, off-topic, can anyone recommend a solid binary file editor that runs in UNIX? I have been using HexEdit for Windows and I would prefer to run only in UNIX. Thanks, E. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
