Similarly, the function -string()- takes a numeric format as argument,
which could be a leading zero format.

You cannot -replace- the numeric variable because -replace- cannot
promote
the data type to -string-. Just create a new variable, then:

gen newx="0"+string(x)

You could also -format- the numeric variable -format x %02.0f- to
achieve a
similar effect, without changing the actual contents of the variable...

Can you show me how I can generate ID in the following manner: 01,
02..... instead of 1, 2, 3...?

>From the original data, I have ID in the form of 1, 2, ...... I then
use the following commands:

tostring ID, replace
replace x = "01" if x=="1"

There was a message "type mismatch".
