Thank you for the help guys, seems like converting the int to a str will solve the issue!

First off I'd like to apoligise if this has been answered before, but an hours google search came up with nothing.

I am writing a macro to imrpove some instrumentaton in my lab (postgrad) and I need it to do the following basically,

Run experiment (data is saved as Scan.txt)

Take saved data and append the filename with a "1" e.g. Scan1.txt

Run experiment again (new data set saved)

Take saved data and append the filename with a "2" e.g. Scan2.txt

etc.

for about 100 iterations. I think my limited experience is good enough to complete the macro except for the writing of filenames. What I have so far is something along the lines of :-

variable N1 is the iteration variable

Repeat (Repeat 100 times)

Run experiment

Renamefile "Scan.txt" to "Scan + %N1% .txt"

End repeat

Thats basically all I need however the code needed for line 3 is completely lost on me. Any help would be greatly appreciated.

Thanks,

Shane
