Change in the data record from comma to a full stop (dot)

[Lisa Schulze]

Hi everybody,
My question is if somebody know how I could change in my data record a comma to a full stop. Do you know if there is a command like this to change all commas to full stops (dots).
Thanks for your help!

you don't really give enough info for a full answer; however, reading you literally, I suggest you look at

help subinstr

if, instead, you are talking about your output, you want to look at "set dp"; see
