From my examination, the define of QUERYCVT is dependent on the definition of __FX. __FX is defined in features.h. So, first off, have you #include'd <features.h>? Within this file, __FX is dependent on the LE level and on _OPEN_SYS_FILE_EXT being defined. From looking in the manual, if appears that you may need to have the statement: #define _OPEN_SYS_FILE_EXT 1 in your source code before the #include of <fcntl.h>. Wish I could test this for you, but we are not licensed for the C compiler. -- John ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
