Hi All

Assuming I have appropriate permissions on the file system can anyone tell me if it is possible to copy/move from a UNIBASIC program?

I have explored READBLK and WRITEBLK but the file always seems to be corrupt after writing.

Example scenario; move/copy a word doc or PDF file from one directory to another.

Alternatively is there a way to shell execute a command to the local server or execute a powershell command etc.

Thanks In Advance
Aaron

Aaron,

Why not use the EXECUTE command to execute a shell level command.
For Windows EXECUTE " DOS /c 'copy xxx xxx' "
For UNIX EXECUTE " sh -c 'cp xxxxx xxxx' "

Thanks,
Jonathan

    Aaron, looks like you are using UniVerse.  I don't remember my UniVerse days very well.  But in UniData before doing any binary reads/writes I would always use NOCONVERT to stop the conversion of null.   To execute an OS command from UniBasic I would always use PCPERFORM or start my command with a ! character.

    @David Green

    NOCONVERT is not available in UniVerse.
    PCPERFORM is also not available in UniVerse.
    For UniVerse to run a shell command is 'DOS /c' on Windows  and 'sh -c' for Unix but the command has to enclosed in single quotes.

    Hello
    Best practice is a os statement.
    On windows use 'DOS /C stmt' it start a cmd.exe and execute stmt. 
    on Unix use 'SH-c statement' it start a SH and execute stmt. 

    I hope this help

    Thanks all.

    I was never aware i could use EXECUTE() to run a dos command. A cursory glance at the Unibasic Command Reference doesnt give any hint that I can do as suggested and execute a DOS command.

    And to clarify; yes I am using Universe on Windows.

    Thanks Again.
