| Pattern A |
|
The instruction is converted without any changes. |
|
|
| Pattern B |
|
With GP-Pro EX, variables with different lengths can not be allocated on one instruction. In case that the bit lengths of variables allocated on SAL instruction are different, the convert instruction to match the variable lengths is added and converted.

After Conversion |
|
| 1. |
An instruction to copy the data of "Int_a.B[0]" to 8 lower bits "Int08TmpTran(0).B[0]" of the integer variable "Int08TmpTran(0)" is created.
|
| 2. |
The bit of the integer data stored in "Int08TmpTran(0)" is shifted to the left for the number of "Int_b" bits. The result of the operation is stored in "Int32TmpTran(0)".
|
| 3. |
An instruction to copy the data of 8 lower bits "Int32TmpTran(0).B[0]" of "Int32TmpTran(0)" to "Int_c.B[0]" is created. |
|
 |
|
|
| MEMO |
| * |
The integer variables "Int08TmpTran(0)" and "Int32TmpTran(0)" is created automatically when conversion. |
