Problems with hi2cIn or hi2Cout?

Took me a while to spot that with syntax such as:

HI2CIN [newslave],location,(variable,...)

the square brackets DO NOT mean that the variable is optional (which you might guess, given that this is the nomenclature often used in computer manuals). It means that you literally type the square brackets around the value

Thus :

HI2CIN [%10010010],0,(122,154)
