Except for the non-numerical formats, these may be preceded by a "0" ("zero", not "oh") to pad the
field length with leading zeroes, and a positive digit, to define the minimum field width (which will be
overridden if the specified width is not large enough to contain the number). There is a 24-character
limit to the length of the printed text; longer strings will be truncated.
Examples:
Suppose the text is "76/12/25 23:11:11". Then
set format x # defaults to "12/25/76" \n "23:11"
set format x "%A, %d %b %Y" # "Saturday, 25 Dec 1976"
set format x "%r %D" # "11:11:11 pm 12/25/76"
Suppose the text is "98/07/06 05:04:03". Then
set format x "%1y/%2m/%3d %01H:%02M:%03S" # "98/ 7/ 6 5:04:003"
