To insist on 6 decimal places, use a display format such as %8.6f. Use -format- to assign that before you -list-. I don't know what "the number of columns in a variable" is. However, it helps to remember that to Stata the numbers you hold are all held as binary. If the data were entered with a fixed number of decimal places, you can (attempt to) show the same number of decimal places with an appropriate format, as above. However, as your variable was calculated as a z-score, 6 decimal places are a choice, and in no sense at all are they a characteristic of the data. Seeing 6 decimal places is just a side-effect of your display format %9.0g.
