Re: Weird error on IFS open()

Interestingly, I tried the program that Jon is having trouble with.
My job's CCSID is set to 37, and Jon's code fails with ECONVERT (the same message he posted)

However, if I change the last parameter of open() to 37 (instead of 0 which means "take it from my job's default") it works without error.

This seems strange to me, because they should result in the exact same values. The only difference seems to be that open() doesn't have to figure out what my job is.

Possibly the fact that 0 has the POTENTIAL to be non-SBCS is all it takes to make it fail.

Can anyone suggest why I would get a errno value of 3490 (Conversion
error) on a file open?

You're using O_CODEPAGE with a SBCS ASCII value. This will only work if your job is not using a mixed CCSID. O_CODEPAGE supports only SBCS or DBCS code pages. It does not support mixed (i.e., both SBCS and DBCS code pages). Use O_CCSID for that.
