There must be something I'm missing. You've already done it.
"0 " (zero followed by blank) is not NUMERIC. Your snippet displays "NOT NUMERIC" twice, as it should.
So, what is your problem? |

possibly Ragav86 has overlooked the fact that when NUMERIC is true
the literal has an embedded space,
whereas when
there is no leading space in the literal.
all things considered, you are correct Bill,
but
| Code: |
0 NOT NUERIC
0 NOT NUERIC |
Ragav86 does not see two spaces, only one, and it is because his literals are not defined the same.
that and he misspelled numeric in the NOT literal....... |

Good spot dbz. I can't make any more sense of it than that...
Looking further, the second IF still tests the original field, not the place it has been MOVEd to.
MOVE in Easytrieve is an interesting sort of thing. If you do it at field level it does a MOVE without any conversion, as though both/all fields are defined as A. This can readily trip those used to the way MOVE works in Cobol.
Personally, for fields, I'd always use assignments (=) (other than when you need to use a MOVE :-) ). |
