If this keyword is not used, the number of fields is derived from other keywords (e.g., #!F-adobe-times-bold-r-normal--18* structure #!EF or #!F-adobe-times-bold-r-normal--18* type #!EF ). #!I0 #!N #!N #!N #!N #!I0 #!N Notes: #!N #!I30 #!N 1. The values for the #!F-adobe-times-bold-r-normal--18* name #!EF parameter are strings separated by commas and without quotation marks. #!N #!I30 #!N 2. You must name all the fields in the data file. #!N #!I30 #!N 3. The field names can be used later to refer to individual fields. For example, if you use the Import module to import the data all at once, you can use the Select module to separate out each field by name. Or you can specify the names of the fields you want to import as the #!F-adobe-times-bold-r-normal--18* variable #!EF parameter to the Import module.

If the position values are intermixed with the data in a file, you must specify the positions as a field (instead of using the #!F-adobe-times-bold-r-normal--18* positions #!EF keyword). Use the reserved word #!F-adobe-times-bold-r-normal--18* locations #!EF for the field name. The corresponding value for the #!F-adobe-times-bold-r-normal--18* structure #!EF keyword should specify the dimensionality of the positions (e.g., "2-vector"). #!I0 #!N #!N #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Lformkwd,dxall146 h format #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
