[GiDlist] problem data

Post by Javier Mora »

I don't know exactly the reason, but it seems to be related to the use of a
single-value option for the first question of the prb file.
Check the following:
Using more than one option in the first question:

QUESTION: Unit_System#CB#(SI,CGS,USER)
VALUE: SI
HELP: use coherent units

or swap the two first questions:

QUESTION: Title
VALUE: Default_title
QUESTION: Unit_System#CB#(SI)
VALUE: SI
HELP: use coherent units

Any of both solutions should work...

[GiDlist] problem data

Post by Enrique Escolano »

The problem is a confussion between the first field value "SI" and the reserved word "SingleField"
It exists at this scope (Data Problemdata) two reserved words: "SingleField" and "Escape"

It is a GiD bug in this two cases:
- If your firts problem data field value match a left part of "SingleField" (case insensitive, as in your case "SI")
- If your first problem data field value match the full word "Escape" (case insensitive)

Avoid this bug using for example IS or International instead SI.

QUESTION: Unit_System#CB#(International)
VALUE: International
