Prompts
The prompt message may be up to 24 characters long and may contain
any legal ASCII character (see Appendix A for an ASCII reference table)
except those shown in the following table.
Value Display Format
Enter the Value Display Format using the # character as a place holder to
denote significant digits. Use a decimal point (.) as necessary for decimal
information. To display the value as a positive or negative signed
quantity, place a + character at the beginning of the value display format.
Without the + character, only the magnitude of the value is displayed. For
example, a format of ### displays integers between 0 and 999 inclusive,
while a format of +### displays integer values between –999 and +999.
When you use a value display format, the number of characters used to
display a value is always the same, regardless of the value. Leading
spaces and trailing zeros are automatically added to fill out the defined
format. If the current absolute value of the variable is too large to be
displayed using the specified value display format, it is displayed as a
field of Xs. For example, if a value display format of ###.### is used to
display a variable with a current value 1000.3, the resulting display is
+XXX.XXX. Note that the value display format affects only the
displayed value, not the entered value. See Range Limiting for more
information on limiting the range of entered values.
