I realy don't know why they designed it that way but sometimes this odd behaviour can drive you crazy if you don't use this silly (and it works !) solution. One example is storing all earnings and payments in one field using another as a flag.

Amount Flag
100000 Income
200000 Payment
200000 Income
......

select iif(flag = "Income", 1,0)*amount as Income, iif(flag = "Income", 0,1)*amount as Payments

leads to many income and 0 payment (or reverse if the first is Payment). Again using a big number enough as a multiplier instead of 1 resolves the problem (even if in VFP5 it's still like that). And this behaviour is true for character fields that are based on an expression rather than a field (and I use padr() or something like that for those).
