ENFORM Reference Manual

4 Statements
058057 Tandem Computers Incorporated 4–1
This section contains the syntax of the ENFORM statements. The statements are
arranged in alphabetical order to provide ease of access.
The ENFORM statements, with the exception of the LIST and FIND statement, have a
session-wide affect unless cancelled or overridden. The LIST and FIND statements
effect only the queries of which they are a part.
The AT END, AT START, FOOTING, SUBFOOTING, SUBTITLE, and TITLE
statements apply only to queries containing a LIST statement. These statements
supply information to be printed in a report.
The LIST and FIND statements must be terminated with a semicolon. The other
ENFORM statements should be terminated with a semicolon. ENFORM neither
executes the statement nor reports any syntax errors until it encounters either a
terminating semicolon or the keyword indicating the start of the next statement;
therefore, if you enter a ?SHOW command after a statement without a terminating
semicolon, the effect of the statement is not shown in the output produced by the
?SHOW command.
Table 4-1 shows the ENFORM statements and their functions.
