Applicable Program Areas
Operands Bs: Source Base Address
Specifies the source base address. The offset is added to this address to cal-
culate the source word.
Of: Offset
The value of Of determines the operation of COLLC(567).
• Data Collect Operation (Of = 0000 to 7999 BCD)
The Of value is added to the base address to calculate the source word.
The offset can be any value from 0000 to 7999 BCD, but Bs and Bs+Of
must be in the same data area.
• LIFO Stack Read Operation (Of = 8000 to 8999 BCD)
If the leftmost digit of Of is 8, COLLC(567) will operate as a LIFO stack
instruction. The stack begins at Bs with a length specified in the rightmost
3 digits of Of.
• FIFO Stack Read Operation (Of = 9000 to 9999 BCD)
If the leftmost digit of Of is 9, COLLC(567) will operate as a FIFO stack
instruction. The stack begins at Bs with a length specified in the rightmost
3 digits of Of.
