6.6.4 System interface Questions of system interface generally fall outside of the domain of this report. However, the following operations are important enough to deserve description here. Filename should be a string naming an existing file containing Scheme source code. The load procedure reads expressions and definitions from the file and evaluates them sequentially. It is unspecified whether the results of the expressions are printed.
Load returns an unspecified value.
Its operation on other kinds of files necessarily varies among implementations. Filename must be a string naming an output file to be created. The effect of transcript-on is to open the named file for output, and to cause a transcript of subsequent interaction between the user and the Scheme system to be written to the file. The transcript is ended by a call to transcript-off, which closes the transcript file. Only one transcript may be in progress at any time, though some implementations may relax this restriction.
