error apparent function SetAsInput and SetAsoutput no TRISA action

[alexpseletr]

I'm using the code below to test it. 1) TRISA is not changed in the assembler 2) trisB manually in asm it appears as PORTB, in the simulator the TRISB is triggered (in trisB it should be only the name of the variable)

program NewProgram; {$PROCESSOR PIC16F84A} {$FREQUENCY 4MHZ} uses PIC16F84A;

//Declarations here

begin

SetAsInput(PORTA_RA0); TRISB:=$FF;

end.

I see the ASM code is right. It's an issue of the disassembler. Take a look to https://github.com/t-edson/PicPas/issues/19 If you simulate the code, you will see TRISA and TRISB are changed. It's just the disassembler doesn't know that the current bank is 1, when found the Opcode BSF, because the PIC ASM Opcodes don't have bank information.

TRISA also does not appear in the simulator, in Proteus I also had strange operations in some test codes ...

maybe we should change the way that SetAsInput and SetAsout get the parameters ... or something like that

Why TRISA doesn't appears (and why appears some other unused registers), is another issue, maybe a strange feature. Anyway you can add it, manually (if cannot, it's a bug). The simulator is still experimental so there is much work to do in it. PicPas simulator only simulates the CPU core. Proteus has some bugs too. Probably there are differences in execution.

This problem should be solved in the version 0.8.4.
