FPWIN PRO vs. FPWIN GR

I have basic knowledge about PLC programming and I'm using FP0 Sequence, I'm confusing in choosing FPWIN PRO or FPWIN GR to program. I haven't understood clearly the diffirence between FPWIN PRO and FPWIN GR. When we should use FPWIN PRO and when we should use FPWIN GR ?
The other thing is FPWIN GR don't include ONLINE HELPS or exambles like FPWIN PRO. Where I can find it ?
Please help me.

Thanks a lot.

Depends on what you need to do.

FPWinGR is only ladder logic and FPWinPro supports all five languages.

If you have simple program, basic I/O use GR
If you have extensive process control, string conversion and another one million things requiring better programming language use PRO.

basically they tell you here the differences
