| Source |

Example
readfile (lbfile, rec_lbf)
lay_emp.dept := rec_lbf.dept
lay_emp.empnr := rec_lbf.empnr
lay_emp.salary := rec_lbf.salary
lay_hdr.hdept := rec_lbf.dept
level_break (rec_lbf.dept, lay_ftr, lay_hdr, 3)
average (rec_lbf.salary, lay_ftr.avgsal)
minimum (rec_lbf.empnr, lay_ftr.minemp)
variance (rec_lbf.salary, lay_ftr.varsal)
print (lay_emp)
endread
lay_emp.dept := rec_lbf.dept
lay_emp.empnr := rec_lbf.empnr
lay_emp.salary := rec_lbf.salary
lay_hdr.hdept := rec_lbf.dept
level_break (rec_lbf.dept, lay_ftr, lay_hdr, 3)
average (rec_lbf.salary, lay_ftr.avgsal)
minimum (rec_lbf.empnr, lay_ftr.minemp)
variance (rec_lbf.salary, lay_ftr.varsal)
print (lay_emp)
endread
