Informix uses the
.eco,
.cob and
.mf2 file extensions. For CP to resolve copybooks and include statements correctly, use the following COBOL Compiler directives:
copyext(eco,mf2,cob,cpy,cbl) osext(eco)
Informix only produces error messages in its list files. Normally the error message will contain the line the error occured on. If COBSQL cannot locate the line number from the error message, it will not report the error.
To run COBSQL correctly with Informix, the INFORMIXDIR environment variable should be set before using COBSQL.
