Re: VarChar to Char Field, Shouldn't This Work?

I have a RPG field defined as VarChar(17) and a file field defined as

EDI850_Detail_Out.UnitPrice = EDI850_PO1_Record.UnitPrice

In the above, PO1 is the varchar field. I am getting the following
error: "Length of varying length variable is out of range."

Am I forgetting something? My head has been stuck in the .NET world a
bit too long me thinks....

I believe the error [rnq0115 rnx0115] implies that the 2-byte length attribute of the varying character variable is in error already, rather than any relationship to the ability to assign between fixed-length char and varying-length char. If so, the question is how did that variable with the incorrect length get set? Review the value in debug before that assignment is attempted. Knowing what is the incorrect value for the length may assist to track back to the assignment or other origin [e.g. initialization, basing pointer being set, etc.] for the length attribute of that variable.

A varying 17 takes 19 bytes of storage. If the value of the string is 'ABC' then the storage is x'0003C1C2C3'; i.e. a length attribute of x'00003'.

However if, for example, the raw value x'C1C2C3' either had been /moved/ into the varying field or is defined by an overlay\direct-map, then the variable would look like the string 'C.....' with a length attribute of x'C1C2' which is out-of-range; i.e. a length _way beyond_ 17.
