Abstract: A data name standardizing/unifying system for standardizing the names of data belonging to data items having different names and transferred or compared among data files so as to be unified for programs. For standardizing the data names, names of data items assumed to have same contents are gathered and a table indicating data names to be replaced are generated to be displayed together with prompting for entry of the standard data name to replace. From this table, standardization for data names is accomplished by this replacement of the data name in the programs. For identifying the standardized data names created for the different files, different file names or different and upper file names are added to a division of program which refers to the files.

Abstract: A wall of a building is constructed by joining a plurality of partition units of substantially U-like cross-sectional shape. During storage or transportation, the partition units are grouped into a telescoped assembly by forcing each partition unit into the internal space of another. During construction of the wall, the partition units are successively drawn to be joined together while being engaged at the upper or lower end thereof by a guide member thereby providing continuous flat partition wall surfaces. Then, a filler material is usually filled in the internal space of the joined partition units to complete the wall, but such filling work can be dispensed with where ready installing and disassembling is desired or where insulation against heat and or sound is not required.
