Format specifications can include nested format specifications enclosed in parentheses; for example:
15 FORMAT (E7.2,I8,I2,(A5,I6)) 35 FORMAT (A6,(L8(3I2)),A)
A group repeat specification can precede a nested group of edit descriptors. For example, the following statements are equivalent, and the second statement shows a group repeat specification:
50 FORMAT (I8,I8,F8.3,E15.7,F8.3,E15.7,F8.3,E15.7,I5,I5) 50 FORMAT (2I8,3(F8.3,E15.7),2I5)
If a nested group does not show a repeat count, a default count of 1 is assumed.
Normally, the string edit descriptors and control edit descriptors cannot be repeated (except for slash), but any of these descriptors can be enclosed in parentheses and preceded by a group repeat specification. For example, the following statements are valid:
76 FORMAT ('MONTHLY',3('TOTAL')) 100 FORMAT (I8,4(T7),A4)
