ne of a piece GPIB equipment? I am wanting the user to input a decimal value and then send that decimal value in the command line string to the equipment. Am I going to have to do some data conversion here or is there an easier way??? Thanks in advance!

Once the instrument is installed in the system (that's
the bd[InstrID] part), just print the value into a string
in the format dictated by the instrument manual, then use
ibwrt to upload it to the instrument.

ps. As a beginner you might want to use sprintf() rather
than Fmt(). I have never yet found anything that
sprintf() and sscanf() couldn't cope with, and the
learning curve on Fmt() and Scan() shouldn't be
attempted without oxygen!

Fmt (WriteBuffer,"%s

// write formatted string to GPIB - set desired units
ibwrt(bd[InstrID], WriteBuffer, NumFmtdBytes ());

Call it something unique. That name will be the control ID. In your program use GetCtrlVal(panel, controlID, value);
Then the value of the numeric control will be saved in the parameter called value. Manipulate that number however you want. You will need to define the variable somewhere in the top of the FCN.
