2.2 Configuration

These constants and procedures describe characteristics of the Scheme and underlying operating system. They are provided by all implementations.

Constant: char-code-limit

An integer 1 larger that the largest value which can be returned by char->integer.

Constant: most-positive-fixnum

In implementations which support integers of practically unlimited size, most-positive-fixnum is a large exact integer within the range of exact integers that may result from computing the length of a list, vector, or string.

In implementations which do not support integers of practically unlimited size, most-positive-fixnum is the largest exact integer that may result from computing the length of a list, vector, or string.

Constant: slib:tab

The tab character.

Constant: slib:form-feed

The form-feed character.

Function: software-type

Returns a symbol denoting the generic operating system type. For instance, unix, vms, macos, amiga, or ms-dos.

Function: slib:report-version

Displays the versions of SLIB and the underlying Scheme implementation and the name of the operating system. An unspecified value is returned.

(slib:report-version) ⇒ slib "3b6" on scm "5b1" on unix
Function: slib:report

Displays the information of (slib:report-version) followed by almost all the information neccessary for submitting a problem report. An unspecified value is returned.

Function: slib:report #t

provides a more verbose listing.

Function: slib:report filename

Writes the verbose report to file filename.
