via “multi-dialect cobol syntax highlighting with fixed-format margin support”
IntelliSense, highlighting, snippets, and code browsing for COBOL and more
Unique: Explicitly supports COBOL fixed-format column structure (columns 1-6, 7, 8-11, 12-72) with visual margin indicators, and covers 5+ COBOL dialects plus related mainframe languages (JCL, PL/I, HLASM, REXX) in a single extension — most competitors focus on single dialects or free-format only
vs others: Broader dialect coverage and fixed-format awareness than Rocket's official extension or generic COBOL plugins, making it suitable for heterogeneous mainframe environments with legacy code
