When editing or retrieving Cobol element using vscode Explorer for Endevor extension, there is no file extension on the file name, and could not benefit from the Cobol LS syntax highlighting feature.
Release : 18.1
Component : EXPLORER FOR ENDEVOR
Explorer for Endevor - v0.12.0
Explorer for Endevor does not add file extension, if FILE EXT is blank in cobol type definition, retrieve/edit of the cobol element in vscode Explorer for Endevor will show no file extension.
The solution is to update the Cobol Type definition in Endevor, add either "cbl" or "cob" to FILE EXT, since COBOL Language Support recognizes files with the extensions .cob and .cbl as COBOL files.
