2.1 General KAP Information

The following provides information and restrictions:

• The following command qualifiers provide maximum general optimization: /optimize=5, /roundoff=3, /scalaropt=3 . These are the default settings for these qualifiers.

  See Section 2.3 about KAP execution using the kfort driver for an explanation of how to pass command qualifiers to KAP and Chapter 4 for details about what is controlled by each qualifier's levels.

• If a FORMAT statement for a Hollerith constant is continued on a second line and the first line has trailing blanks, KAP removes the trailing blanks, causing an error message from the Digital Fortran compiler. This is also true for quoted strings that are continued over more than one line.

  To avoid this problem, put the entire string on one line, or terminate the first line of the Hollerith constant with something other than a blank.

• KAP is not case sensitive by default.

• KAP does not optimize loop nests with noninteger indices, such as:

  DO 100 x=0.0, 10.0, 0.2
  

• KAP does not support Fortran EXTERNAL * <name>.
