RE: MOVEL in freeform

Scott,

I'm curious, if this function shouldn't be used the OP's purpose, then what should it be used for?

It seems to me that it's designed to convert from a zoned decimal value stored in a character buffer
to an integer. Is that not the case?

The OP had "00000000M" and needed to convert it to -4.

int QXXZTOI(unsigned char *zptr, int digits, int fraction);

Thanks!

Hi Alan,

D cvtZonedToInt pr 10i 0 extproc('QXXZTOI')
d cvtZone * value options(*string)
d cvtDigits 10i 0 value
d cvtFraction 10i 0 value

You should remove 'options(*string)' from the first parameter. The
input isn't a string, it's a zoned decimal number.

I have no idea why you'd want to use this for your purposes, though. Is
your goal really to convert zoned decimal to integer? And if it is,
why use a C function? Why not use %int()?

AFIAK, your issue is thast you have bytes in zoned decimal format, but
they've been stored (for some weird unknown reason) in an alphanumeric
field instead of in a zoned decimal field.

The solution to that is to use overlaid fields in a data structure.
Though, you can solve the same problem by passing a mismatched parameter
(which is what you've done by calling QXXZTOI) or by pointer logic.

But, an overlaid data structure field would perform a lot better than
calling this API, and it'd also make a lot more sense to the next guy
reading your program.
