bon, c'est bien simple, il semble que antlr 4 génère les chiffres en fonction de la locale, c'est-à-dire, en français : avec une virgule. et c'est dommage, parce dans ce cas, postscript n'en trave que dalle.

the solution problem simple. seems antlr 4 generates numbers using locale, i.e. in french, using comma. it's pity because postscript not understand french (latin?) floating numbers.

you should fill study antlr 4.

on unix, can temporarily alter locale on bash

export lang=c
