Alloc function does not work as expected

[x87]

Alloc(s$txtGlobalDealerZoneName, 9451) // s$9451 {??? Type 0xA Var 0x0010 $4} - does not support s$ and v$ variables

Alloc($txtGlobalDealerZoneName, 9451) // s$9451 {Error: Global variable -9451 is out of range.) - Ranges check throws an error on an allocated variable (since 3.3.0). Workaround is to disable "Ranges check" in the options.
