| DESCRIPTION | This option is like a brief data dictionary listing. Along with thefile and field names are the corresponding table and column names. Italso shows the field's type, like word-processing or set-of-codes. Ifthe field is a pointer, the pointed-to file/subfile number is shown. Ifthe field is within a subfile, the number of the parent file is shown. In this way, all files and fields can be displayed at one level, withoutthe indentation needed with the usual hierarchical display format. Butto find out how files are linked, you may need to follow a long chainfrom one link to the next. The fields global location is also listed. The $PIECE syntax is usedwhen the field is from a particular piece of a global node. The $EXTRACTformat is used when, like for MUMPS-type fields, the location is anextracted portion of the entire node, say from character 1 to 245. Forcomputed fields, of course, there isn't a global location since these arevirtual fields that only perform calculations. |
