 |
|
I thought ZBasic allowed increment/decrement of a given memory address like BasicX but I cannot get the compiler to generate it. The following Basic program:
| Code: | Private I as Integer
Sub Main()
I = I + 1
End Sub |
generates the ZBasic virtual machine code of: | Code: | PSHA_W 0x00a0 (160)
INC_W
POPA_W 0x00a0 (160)
RET |
whereas BasicX generates: | Code: | incI test.i ' (354)
halt |

It did. That code generation optimization was inadvertently disabled in conjunction with some other changes. It has been restored in the current development version but has not yet been completely tested. |

| This problem has been corrected in v1.1.4 of the compiler. See the Download page for the installer containing the updated compiler or the compiler may be downloaded separately. |
