p-code question

[iskeletors]

0A 36 00 04 00 ImpAdCallFPR4
35 44 FF FFree1Var
FD A0 37 00 Lead2/ImpAdLdUI1 (imports the value of the address and loads it to the register I think)
FC 14 Lead1/CI2UI1 (converts the value I think)
F4 00 LitI2_Byte: -> 0h 0

I have a p-code like that. How can I write "1" to the same address whose value is imported at the third line. Thanks for your helps by now.

Regards.
