If I have an element with a name of:
GVCCS1 4 0 5 0 1.25
Then the parser, in the course of trying to do string substitution on VCCS (later on the line), inadvertantly also replaces the "VCCS" that is part of the element name. i.e. the above line gets turned into this:
G 1 4 0 5 0 1.25
and then subsequent steps get confused by the extra number.
Thank you for your efforts and support,
