Annotation of loncom/html/adm/help/tex/Spreadsheet_Op_On_All_Problem_Parts.tex, revision 1.1
1.1 ! bowersj2 1: Often, there are several parts in a specific problem. For example, a
! 2: problem with three parts would have parts 0, 11, 12, and 13. For a
! 3: general spreadsheet, it is not often desirable to sum up all of these
! 4: parts, while not knowing how many parts there are as the spreadsheet
! 5: is written.
! 6:
! 7: The spreadsheet has a preprocessor which an expand a symbolic
! 8: expression over all symbolic names that fit. The general syntax is
! 9: \texttt{[\&EXPANDSUM(VARNAME;expression)]}.
! 10:
! 11: For example, for the above assessment with three parts,
! 12:
! 13: \texttt{[\&EXPANDSUM(\textbf{PART};parameter_\textbf{PART}_weight*stores_\textbf{PART}_awarded)]}
! 14:
! 15: would become
! 16:
! 17: \texttt{parameter_\textbf{0}_weight*stores_\textbf{0}_awarded +
! 18: parameter_\textbf{11}_weight*stores_\textbf{11}_awarded +
! 19: parameter_\textbf{12}_weight*stores_\textbf{12}_awarded +
! 20: parameter_\textbf{13}_weight*stores_\textbf{13}_awarded}
! 21:
! 22: where \textbf{bolded text} is used to highlight what the
! 23: \texttt{\&EXPANDSUM} function is doing.
