Copy list definition list-or-row-name ([Clear list])


Clear list If specified, the command empties the current list and removes its column definitions before executing


This command redefines the column headings of the current list by copying the columns and data structure from the specified list. If the current list contains data and you do not clear the list, no change is made to the internal structure of the list; in this case, columns are neither added nor removed, merely renamed and the command is similar to Redefine list.

When the current list is empty or the Clear list option chosen, the command is the equivalent to 'Define the list so that it matches the specified list'.


Set current list iList1
Define list {iCol1Date,iCol2Num,iCol3Char}
Add line to list
Set current list iList2
Define list {iCol4Date,iCol5Num,iCol6Char}
Add line to list
; now change the definition of iList2 to match iList1
Copy list definition iList1 (Clear list)
; or you can do it like this
Do iList2.$copydefinition(iList1)
