Dumb question about files on a server

[Graham Samuel]

Mike, thanks for that. I think I have not really explained enough about what I want.

I have a .lc script on the server that invokes Jacque Gay’s Zygodact product to generate license codes, which are then passed on to the payment processor. This works fine. However when a code is generated, it would be prudent to keep it in a file which is on the server. So I want to add a few lines of code to the aforesaid .lc script so that each code goes into a text file. I don’t need a database since the list will probably be less than 1K lines (if it gets any bigger, I can create another solution). So none of this activity is taking place outside the server - it’s all happening in a .lc script run by the LC Server engine.

In these circumstances, I thought a fairly straightforward bit of LiveCode coding would do the job. This is different from what you’re suggesting, I think - though I am out of my comfort zone doing this at all.

Can I appeal for more help on this?

Thanks

Graham
