Hello All, I would like to create a .pro routine which reads in a number of consecutive .csv files which are randomly named in the same folder. For instance there might be 100 randomly named .csv files in the same folder. My question is: how do I load these into IDL and assign each of these files a matrix name ie. M1, M2, M3, M4 etc. in order that I can carry out mathematical manipulations on them or visualise them? Thanks, Nevica
