4 Command Qualifiers

This chapter describes the command-line qualifiers of the basic KAP Fortran for OpenVMS ALPHA.

To specify a command qualifier, you can use the long name or short name. Additionally, you can specify command qualifiers on the first line of the source file. (See the description of the C*$* qualifier line at the end of this chapter.)

Note

The short names for qualifiers are provided for the convenience of interactive users. Since the short names may not be unique in future versions of KAP, the long names should be used when compatibility between versions is required.

Many KAP command qualifiers can also be set with inline directives or assertions.

Table 4-1 lists the command qualifiers. The first column lists the long name of each qualifier, and also shows the functional categories of qualifiers as follows:

• General optimization

• Parallel processing

• Fortran dialect control

• Directive control

• Inlining/Interprocedural Analysis (IPA)

• Input/output

• Listing

• Advanced optimization control

The next two columns list the short names and default value of each qualifier.

Note

A backslash (/) is required before each qualifier name, but the hyphen is not shown in Table 4-1.

Table 4-1 Command-Line Qualifiers

The subheadings in the following sections list the long and short names for each qualifier, followed by its default in parentheses.

Unless otherwise noted, the code examples in this chapter were run with /optimize=5, /scalaropt=2, /roundoff=2 , and /unroll=1 .
