Hi all I am making good progress loading a CSV file into mmbasic so I can pre-program data in a spreadsheet. I export from the sheet as CSV and it creates a generic "namexxx.csv" file name. I can access the file from mmBasic no problem using Open "" for input as Now I would like the program to search the card and identify the first .csv file it encounters so I may read it, without needing to name the file in advance. When I use dir$ I get a flag error... I am not sure of the nomenclature, and can't find it in the manual. ChatGPT is unable to help too. I can't find any use of dir$ on fruitoftheshed. Can anyone help? Thanks Jo |

Something like this should work.You would need to enhance it to search the directories if that is not known. dim first$,f$ ' chdir("/") chdir("/tests") f$=DIR$("*.csv",FILE) first$=f$ 'Print #1, f$+":--all" 'Print #1, f$ ? " Added... "+f$ Do While f$ <> "" f$=DIR$() if f$<>"" then 'Print #1, f$ ? " Added... "+f$ endif If first$ = "" Then first$ = f$ LOOP ' chdir("/") Latest F4 Latest H7 |
