[C400-L] First SQLC - Program - Why fetching only 1 row?

["Chris Wolcott" <CWolcott@xxxxxxxxxxxxxxxxxxxxxx>]

I am trying to write my first SQLC program to get a file field
description from QSYS2/SQLCOLUMNS.  It compiles fine.  When I run it the
COUNT(*) retunrs 18 into :cnt, which is correct for the specified file.
However, the FETCH only returns 1 row.  I can not see *SQLCA in debug.
(We are coding for V4R5M0)

Also, if I try to add a 'printf' command, the SQL parser chokes on the
edit string saying it is not delimited.  How can I do regular C and SQL
if the SQL is going to try to validate all my non-SQL C code?

I tried COL_NAME & COL_DFT as VARCHARs as well, no difference.  I tried
to FETCH FOR :cnt ROWS, still no difference.

CALL CPYIFS2DB2 PARM('IFS.FILE' 'DB2FILE *CURLIB ')

Here is my code:

EXEC SQL 

  FETCH FLDCUR

  return(cnt);
