postscript variable syntax (.ps file)

Question

Hi - I have a large .ps file. There are some variables defined but I am not able to figure the length of the variable.

I am picking some part of the code, it is like a four column and multiple row matrix.

 .../$v.HDLE_UNIT_TOTAL ex 31.752 103.752 220.4 2 10.0 0.0 0 vsE  //31.752 must b x axis?
 /$v.PKGE_QTY_TOTAL ex 69.48 213.48 220.4 2 10.0 0.0 0 vsE....   //213.48 must b y asix?
   // what defines the length of that variable?

Answer 1

It is completely impossible to say what this PostScript snippet does without access to the complete PostScript program/file.

At the very least one needs to know what vsE means. This must be defined elsewhere in the file (more to the front in a statement similar to

/vsE {some-PS-code} def
