2.1 General KAP Information

The following provides information and restrictions:

The following command switches provide maximum general optimization: -optimize=5, -roundoff=3, -scalaropt=3 . These are the default settings for these switches.
See Section 2.3 about KAP execution using the kf77 driver for an explanation of how to pass command switches to KAP and Chapter 4 for details about what is controlled by each switch's levels.
The default input line length for DIGITAL KAP for DEC Fortran is 72 columns. You can specify longer lines with the -scan command switch.
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 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. See the description of the -case command switch in Chapter 4 for instructions on how to make KAP case sensitive.
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>.
