C.3 Hollerith Format Specification

A format specification may be an array name of type integer, real, or logical. In this case, the leftmost characters of the specified entity must contain Hollerith data con- stituting a legal format specification. Blank characters may precede the format specification and data may follow the right parenthesis ending the specification with no effect.

A Hollerith format specification must not contain an apostrophe edit descriptor or an 'H' edit descriptor.

C.4 'A'Editing Of Hollerith Data

The' Aw' edit descriptor can be used with Hollerith data if the corresponding 110 list item has type integer, real, or logical.

Editing is as described for' A' editing (section 6.4.3.1.1) of character data, except that 'n' is the maximum number of characters that can be stored in the storage unit of the list item.
