Importing JCAMP files for IR Spectra

Hello,
I am fairly new to IGOR and I am trying to upload some spectra from the NIST database in JCAMP dx file format. I am not super computer savvy, but I have been looking through the manual and found info (listed below) but I cannot figure out how to execute the commands or find the proceedures mentioned. I know this is probably fairly simple task, but I think I need a step by step explanation of where to find this procedure and how to go through it. Sort of the "for dummies" version, if you will. Can anyone help me out with this?

"Loading Row-Oriented Text Data
All of the built-in text file loaders are column-oriented — they load the columns of data in the file into 1D
waves. There is a row-oriented format that is fairly common. In this format, the file represents data for one
wave but is written in multiple columns. Here is an example:
350 2.97 1.95 1.00 8.10 2.42
351 3.09 4.08 1.90 7.53 4.87
352 3.18 5.91 1.04 6.90 1.77
In this example, the first column contains X values and the remaining columns contain data values, written
in row/column order.
Igor Pro does not have a file-loader extension to handle this format, but there is a WaveMetrics procedure
file for it. To use it, use the Load Row Data procedure file in the “WaveMetrics Procedures:File Input
Output” folder. It adds a Load Row Data item to the Macros menu. When you choose this item, Igor will
present a dialog that presents several options. One of the options treats the first column as X values or as
data. If you specify treating the column as X values, Igor will use it to determine the X scaling of the output
wave, assuming that the values in the first column are evenly spaced. This is usually the case."
