Re: Upgrade to V4R3

[John Hall <jhall@xxxxxxxxxxx>]

The problem is most likely related to an upgrade of the compiler and the
way it handles uninitialized fields or the Z-ADD op.  On a virtual
machine level it is probably trying to load the number to be initialized
into a numeric register before zeroing it and this is causing the error.

If the LDA area has blanks you should not be moving that into a numeric
field anyway.
It's a cheat that worked in the past. 

A possible solution would be to load the LDA into a character Field and
test for blanks before proceding.  Or a Move 0 instead - but this would
still be a cheat.

In the past blank was equal to 0 (S36 days) but it seems that IBM is
getting stricter on the data rules within the RPG compiler.  I believe I
ran into a few similar problems going from V3R2 to V4R2 about a year
ago.
