Connecting a schema holder Example 28 shows how the ABL to SQL correlation is logged in the dataserv.lg file, when the FOR EACH statement is compiled. FOR EACH Customer: DISP NAME. END. Example 28: Using PRGRS_LOG_ABL switch to log ABL to SQL correlation The log output shown below, includes the ABL module name and the line number where the ABL procedure started in correlation to the SQL queries executed on the foreign data source. Visual delimiters are also logged for clarity in the log files.
