Problems with CEE date APIs

["Alan Moulsdale" <alan.moulsdale@xxxxxxxxxx>]

Hello,

I am trying to write a program to calculate the last Friday of the month.

I decided to use the CEE date APIs in a ILE RPG program.

My problem is that the CEEDAYS API will only work if I place a DSPLY
directly after it! This is obviously not desirable.

I have found this to be the case at both V3R2 and V4R4.

Can anybody see what I am doing wrong?

Many thanks

Alan
