%PATHCODE values for assembler programs

This table shows the possible values for the z/OS® Debugger %PATHCODE variable when the current programming language is Assembler:

%PATHCODE	Entry type	Instruction	Additional requirements or comments
1	A block has been entered.	Any	External symbol whose offset corresponds to an instruction
2	A block is about to be exited.	`BR R14 (07FE)`
		`BALR R14,R15 (05EF)`	These instructions are considered an Exit only if this instruction is not followed by an valid instruction.
		`BASR R14,R15 (0DEF)`
		`BASSM R14,R15 (0CEF)`
		`BCR 15,x (07Fx)`
3	Control has reached a label coded in the program.	Any	Label whose offset corresponds to an instruction.
4	Control is being transferred as a result of a CALL.	`BALR R14,R15 (05EF)`
		`BASR R14,R15 (0DEF)`
		`BASSM R14,R15 (0CEF)`
		`SVC (0A)`
		`PC (B218)`
		`BAL (45)`	Except BAL 1,xxx is not considered a CALL
		`BAS (4D)`
		`BALR x,y (05)`
		`BASR x,y (0D)`
		`BASSM x,y (0C)`
		`BRAS (A7x5)`
		`BRASL (C0x5)`
5	Control is returning from a CALL.	`Statement after CALL`	If the statement after a CALL is an instruction, it gets an entry here.
6	A conditional branch is about to be executed.	`BC x (47x)`	`x^=15 & X^=0`
		`BCR x (07x)`	`x^=15 & X^=0`
		`BCT (46)`
		`BCTR (06)`
		`BCTGR (B946)`
		`BXH (86)`
		`BXHG (EB44)`
		`BXLE (87)`
		`BXLEG (EB45)`
		`BRC x (A7x4)`	`x^=15 & X^=0`
		`BRCL (C0x4)`
		`BRCT (A7x6)`
		`BRCTG (A7x7)`
		`BRXH (84)`
		`BRXHG (EC44)`
		`BRXLE (85)`
		`BRXLG (EC45)`
7	A conditional branch was not executed and control has "fallen-through" to the next instruction.	`Statement after Conditional Branch`
8	An unconditional branch is about to be executed.	`BC 15,x (47Fx)`
		`BRC 15,x (A7F4)`
		`BRCL 15,x (C0F4)`
		`BSM (0B)`
