Element of a
Conversion Instruction
Meaning
Flags • None: right-justified output
• -: left-justified output
Width • None: output in standard representation
• n: exactly n characters are output. If the output is right-
justified, this may be preceded by blanks, with left-
justified output the blanks come after the characters.
Precision The precision is only relevant for representations A, D, F and R (see
following table).
• None: output in standard representation
• 0: no output of the decimal point or decimal places in
the F and R representations
• n: - with F and R: output of the decimal point and
n decimal places
- with A and D (date): number of digits for the year:
possible values 2 and 4.
Representation The following table contains:
• The possible representations
• The data types possible for each representation
• The standard format for each representation(the printout is in the
standard representation if no width and no precision are specified in the
FORMAT parameter) and their maximum length
The following table shows possible modes of representation in the conversion
instruction of the FORMAT parameter.
