999 999 ONZ Vanilla ISSOM2007 to ISSprOM2019 CRT file 
999 999 Adapted by Michael Wood from the OCAD-provided CRT 
999 999 WITH CHANGES AGREED BY MC AND TC FOR TANKS AND TROUGHS
999 999 THIS VERSION DATED 14 Sep 2019

999 999 I have added symbol names for easier editing
999 999 (since text after the numbers appears to be ignored)

999 999 And I have added those symbols which have not changed
999 999 and those which did not appear in the old OCAD set
999 999 since, for YOUR case, they may well be needed.

999 999 Beware if any of your symbol numbers 
999 999 (perhaps they were your variations on the standard) 
999 999 have been used by IOF/OCAD for a new purpose. 
999 999 There are many, starting with 101.001 heh heh!

999 999 I recommend that any of your symbols which 
999 999 have no symbol in ISSprOM are assigned to (say)
999 999 Out of Bounds area  709.000 (purple cross-hatch)
999 999 Out of bounds boundary 708.000 (a thick purple line) 
999 999 or for point features the Map issue point 702.000
999 999 This will make them stand out, so you will notice
999 999 and can DEAL WITH them on a case by case basis 
999 999 If you end up adding your own new symbols,
999 999 be VERY wary about using .001, .002 etc as Mr OCAD
999 999 may well use them in the future. Recommend .900 etc

999 999 Though OCAD's CRT drops the .000 suffix, I have added
999 999 them, the numbers are more easily read if they line up
