I don't know anything about visual encription.
If it changes with every word and depends on the writer's whims, how can the writer read it later himself?
Regarding the assumption that VMS was written in Hebrew, what about the following two observations: 1) the VMS text looks writen from left to right (see the incomplete lines, they start on the left and end in the middle of the page). Hebrew writing is from right to left.
2. The Hebrew alphabet has only 22 letters, while in VMS some 37 symbols can be distinguished (indeed, for
example Currier's transliteration uses all Latin characters plus 9 numerals
plus the asterisk, the total of 37 characters). If Big Jim's hypothesis is
adopted, the above questions have to be addressed.

Best to all, Mark
