DXYZ

SYMB 0,,,2,0.2

This opens file MAG.XYZ and selects the second Z column to be read into the Z buffer. The Z data will be read as a maximum 8-character text string. Only lines and tie lines less than or equal to 1000 will be read. The DXYZ command reads the first line of data and the SYMB command plots a '+' symbol at each data location. The DPST command posts the Z values 0.15cm right of the symbol, 0.1cm down and left justified. A new attribute named 'post' is defined and the posting text will be 0.2cm high.
