Tangerine was a program for OS9 that build a matrix from a set of HAL vectors to facilitate the construction of MDS figures on the Mac platform.

To build a matrix for tangerine
vecs -m [input matrix] -o [new matrix] -n 100 (# of columns) -D -r
< vocab list
-D don’t dump to std output
-r Use RCS (ie, normalize the vectors)
?-s skip squeeze
This creates new HAL style matrix with n columns

Next step is squish program -takes HAL matrix and makes tangerine matrix
squish [matrix] [out]
squish takes two arguments.
So use ResEdit to set file type and creator
Could also use snitch
