## 12.6.4 BLANK Specifier

The BLANK specifier indicates how blanks are interpreted in a file. It takes the following form:

  BLANK = blnk
  blnk
  Is a scalar default character expression that evaluates to one of the following values:

  'NULL' | Indicates all blanks are ignored, except for an all-blank field (which has a value of zero).
  'ZERO' | Indicates all blanks (other than leading blanks) are treated as zeros.

The default is 'NULL' (for explicitly OPENed files, preconnected files, and internal files). If you specify compiler option /NOF77 (or OPTIONS/NOF77), the default is 'ZERO'.

If the BN or BZ edit descriptors are specified for a formatted input statement, they supersede the default interpretation of blanks.

For More Information:

For details on the BN and BZ edit descriptors, see Section 11.3.4.
