The d must be specified with F, E, D, and G field descriptors even if d is zero. The decimal point is
also required. You must specify both w and d, or omit them both.
A repeat specification can simplify formatting. For example, the following two statements are
equivalent:
20 FORMAT (E12.4,E12.4,E12.4,I5,I5,I5,I5)
20 FORMAT (3E12.4,4I5)

General Rules for Numeric Editing
The following rules apply to input and output data for numeric editing (data edit descriptors I, B,
O, Z, F, E, EN, ES, D, and G).
Rules for Input Processing
Leading blanks in the external field are ignored. If BLANK='NULL' is in effect (or the BN edit
descriptor has been specified) embedded and trailing blanks are ignored; otherwise, they are
treated as zeros. An all-blank field is treated as a value of zero.
The following table shows how blanks are interpreted by default:
Type of Unit of File
An explicitly OPENed unit
An internal file
A preconnected file 1
Default
BLANK='NULL'
BLANK='NULL'
BLANK='NULL'
1. For interactive input from preconnected files, you should explicitly specify the BN or BZ edit descriptor to ensure desired
behavior.
A minus sign must precede a negative value in an external field; a plus sign is optional before a
positive value.
