Hi guys, is there a way to know how many records have been selected after doing a JOIN statement?
For example:
JOIN student_id IN STUDENTS to
     student_id IN COURSES
END

I want to know how many records has STUDENT's file after that JOIN.

Thank you

No data is "selected" after a JOIN statement. You have to execute a data retrieval command (TABLE FILE, MATCH FILE, etc.) before determining the number of rows retrieved.

After the Join Just print STUDENTS tables
TABLE FILE STUDENTS
PRINT
*
ON TABLE
END

Then print the &LINES you will get the number of records .
