REM qbasic program to create BNA file with selected objects based on ID1 | |
REM PROCEDURE: | |
REM | Read a data file which holds ID1 and ID2 of selected objects |
REM | Store ID1 and ID2 in an array |
REM | Read through the complete bna file, one object at a time |
REM | Check if ID1 of this object was present in the datafile |
REM | If present write ID1 and ID2 from the datafile to a new BNA file |
