使用 gixsql 进行预处理会添加不可编译的 gnucobol 代码

Question

I recently started using gixsql for a project I am working on. https://github.com/mridoni/gix/blob/main/doc/gixsql.md

I followed the examples in the readme, but when compiling with GnuCobol the sample TEST001.cbsql is not working:

TEST001.cbsql: in paragraph 'GIXSQL-CI-P-TEST001-EMPTBL':
TEST001.cbsql:394: error: syntax error, unexpected Identifier
TEST001.cbsql: in paragraph '100-EXIT':
TEST001.cbsql:383: error: 'GIX-SKIP-CRSR-INIT' is not defined

If I remove this generated code then the program compiles, although it removes an important section from the program and does not work properly. Just wondering what I might be doing wrong? I am following the example using GnuCobol to compile the preprocessed cobol to connect to a PostGres database.

cobc -x TEST001.cbsql -L /opt/gixsql/lib -lgixsql

Here is the generated section that is causing the compile issue:

GIXSQL*
GIXSQL*   ESQL CURSOR DECLARATIONS (START)
GIXSQL     GO TO GIX-SKIP-CRSR-INIT.
GIXSQL GIXSQL-CI-P-TEST001-EMPTBL.
GIXSQL     CALL STATIC "GIXSQLCursorDeclare" USING
GIXSQL         BY REFERENCE SQLCA
GIXSQL         BY REFERENCE x"00"
GIXSQL         BY VALUE 0
GIXSQL         BY REFERENCE "TEST001_EMPTBL" & x"00"
GIXSQL         BY VALUE 0
GIXSQL         BY REFERENCE SQ0001
GIXSQL         BY VALUE 0
GIXSQL     END-CALL
GIXSQL GIX-SKIP-CRSR-INIT.
GIXSQL*
GIXSQL*   ESQL CURSOR DECLARATIONS (END)

With our Enterprise COBOL compiler I would expect a message along the lines of "A PERIOD WAS REQUIRED" - before starting a new section you have to end the previous sentence with a period . . So try adding a period before GIX-SKIP-CRSR-INIT. :

GIXSQL GIXSQL-CI-P-TEST001-EMPTBL.
GIXSQL     CALL STATIC "GIXSQLCursorDeclare" USING
GIXSQL         BY REFERENCE SQLCA
GIXSQL         BY REFERENCE x"00"
GIXSQL         BY VALUE 0
GIXSQL         BY REFERENCE "TEST001_EMPTBL" & x"00"
GIXSQL         BY VALUE 0
GIXSQL         BY REFERENCE SQ0001
GIXSQL         BY VALUE 0
GIXSQL     END-CALL
           .
GIXSQL GIX-SKIP-CRSR-INIT.

But don't ask me why it isn't generated by your tool...
