Mnemonic: SetCLnk

Hex Code:8JMR00SS00YYHHLL   M=1-7, Compare GPRM R to register YY, indirect set
8JMR00SSKKKKHHLL   M=9-F, Compare GPRM R to constant KKKK, indirect set
9JMRSSSS00YYHHLL   M=1-7, Compare GPRM R to register YY, direct set
9JMRSSSSKKKKHHLL   M=9-F, Compare GPRM R to constant KKKK, direct set
Action:The SetCLnk command sets the destination register "R" (byte 1 lower nibble) to the result of the operation "J", listed below. A compare is then performed, and the link executed if the result of the compare is true.
The indirect form uses GPRM or SPRM denoted by "SS" (byte 3) as the source, as allowed by the operation.
The direct form uses the constant "SSSS" (bytes 2&3) as the source value, if allowed by the operation.
Order:The set operation is performed first.
The compare is then performed, and if the conditions are met the Link is executed.
Comments:It is possible to make this command unconditional by setting "M" to 0 or 8, but the Set command is better suited for performing a set and link as it allows the full range of link commands.
While this command can perform a compare and link, the set and compare share a register, and the command is limited to the link subset.
The related command Set allows the use of seperate registers for set and compare, and also allows the full range of link commands, but cannot combine compare and link in the same command.
Related commands CSetCLnk (conditionally set and link) and CSetLnk (conditionally set, unconditionally link) can combine compare and link, do not share registers but are limited to one constant for either set or compare, and are limited to the link subset.
