The operand fields of SI-format instructions designate immediate data and a virtual storage address.
*--------*---------*----*------------* |Op Code | I2 | B1 | D1 | *--------*---------*----*------------* 0 8 16 20 31
Symbols used to represent immediate data (see HEX40 and TEN in the instructions labeled ALPHA2 and BETA1 below) are assumed to be equated to absolute values between 0 and 255.
Symbols used to represent implicit addresses (see IMPLICIT and KEY in the instructions labeled BETA1 and BETA2) can be either relocatable or absolute.
Symbols used to represent displacements (see DISPL40 in the instruction labeled ALPHA2 below) in explicit addresses are assumed to be equated to absolute values between 0 and 4095.
Examples:
ALPHA1 CLI 40(9),X'40' ALPHA2 CLI DISPL40(NINE),HEX40 BETA1 CLI IMPLICIT,TEN BETA2 CLI KEY,C'E'
When assembled, the object code for the instruction labeled ALPHA1, in hexadecimal, is:
95409028
