General Information

Each EXECUTE block must contain only one ON statement. An ON statement is comprised of the ON parameter and Data Identification statements. Different Data Identification statements are displayed depending on which ON statement is specified.

All ON statements (except ON DATA) display MODE, LINECT, and DATASTAMP parameters, plus Data Identification statement WHEN, which provides conditional execution of subsequent statements based on Data Identification criteria.

See Datastamp Calculation for information about creating unique datastamps. For information about using datastamps, seeDATASTAMP: Functions.

The ON DATA statement does not display MODE, LINECT, DATASTAMP, or WHEN parameters. Instead, conditional or unconditional execution of subsequent statements is provided using IF or ALWAYS Data Identification statements. For more information, see IF: Data Selection Statement, and ALWAYS: Data Identification Statement.
