I have no clue about programming and my knowledge only goes as far as excel! ...was wondering if someone could lead me in the direction of what program to use to do this: I basically need 50,000 numbers, each 11 digits long outputed into a text file (.txt) For example 07850069737 The conditions are: 1st digit must be a zero 2nd digit must be a seven 3rd digit can be a 5 or 7 or 8 or 9 All the other digits are random Each 11 digit number can only appear once in the 50,000. So the text file will list the numbers like this (one number per line) 07859488334 07984304577 07948498357 07543098434 ... I think it's pretty simple but not sure where to start. Thanks in advance!
Try this : Generate Numbers in PHP As i mention it's not unique ... so there is some possibilities (Very small) to have duplicate .
Just a quick note because you said Excel: A google search will help you solving this task even in Excel, no need for a "real programming language" there Third hit on Google for "random number excel" : **tp://answers.google.com/answers/threadview?id=32594
