quick and dirty explanation

AMODE ==> addressing mode ( ANY,24,31)
.. specifies how addresses should be computed 24 or 31 bit,
for any things are more murky,

RMODE ==> residency mode ( any,24,31)
... specifies where the csect shout be loaded ( any,24,31)
below the 16meg line for 24 above the line for 31
same consideration for any

the thing that matter for high level languages is that all
the user csects ( I.E main-program and external subroutines ) should have the same attributes.
System csects ( subroutines ) are usually any,any and they find out by
themselves how to behave

regards

e.s

The POP manual will give a detailed description on how the same instruction
behaves differently ( for AMODE )
