Nested_and_Group_Repeats

 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)
