ecofilename = "filename"
default: none

The ecofilename command is used to provide Palview with the name of the eco opening file created using the companion p3eco program. This eco opening file will be used by Palview to classify each game in the PGN file into its proper ECO code and to provide possible names, which you can provide, for the opening, variation, and subvariation.

Palview3 provides a large eco opening file called p3eco.eco. To use this opening file, you would add this command to your INI file:

ecofilename = "p3eco.eco"

By default, no ecofilename is used by Palview, in which case no eco opening file will be read by the program and no opening classification will be attempted. In this case, the opening information for each game will be taken from the PGN Tags: ECO, Opening, Variation, and Subvariation. (For more information on PGN see the section: Portable Game Notation)

Palview will write the opening information into the game's infobox, as in this next example. Notice that the opening name, Sicilian, appears at the top of the infobox on the left and that the ECO code, B45, appears on the right.

Other INI commands can change the appearance of the opening information in the infobox, such as the tooltipopening command and the gameinfomode command. See those commands for further explanation.
