Command and Query Structure

Character Encoding

3-2
Commands are either set commands or query commands (usually just called
commands and queries in this manual). Most commands have both a set form
and query form. The query form of a command is the same as the set form,
except that the query form ends with a question mark.
Figure 3–1 shows a flowchart of the structure of the commands and queries. The
structure of the header is described in detail in Header on page 3–6.

The program can be described using the American Standard Code for Informa-
tion Interchange (ASCII) character encoding.
This seven-bit ASCII code is used for the majority of syntactic elements and
semantic definitions. In special cases, an eight-bit ASCII Code is allowed in the
arbitrary block arguments described on page 3–6. The ASCII code character set
table is found in Appendix A.
