Note: Registers, when specified alone as in example 4 above, do not default to an
indirection and a length of 4, as other data link values do. In this case, the
data collected is simply the contents of the register.
Examples of Data Link Definition: The following example shows how multiple
TRSOURCE command invocations are used to set up a conditional data link trace.
1) TRSOURCE ID TRC1 TYPE DATA LOC HCPNOS + 34 5840C08C
2) TRSOURCE ID TRC1 DL GB
3) TRSOURCE ID TRC1 IF GB+80.8 EQ C’OPERATOR’
4) TRSOURCE ID TRC1 THEN DL G0:F
5) TRSOURCE ID TRC1 ELSE IF GB+80.8 EQ C’MAINT’
6) TRSOURCE ID TRC1 THEN DL GC.30
7) TRSOURCE ID TRC1 ENDIF
8) TRSOURCE ID TRC1 DL G8
9) TRSOURCE ID TRC1 ENDIF
TRSOURCE ID (Definition Operands)
These TRSOURCE commands could be defined in an EXEC file. In this example, line 1
defines where the trace is defined. Line 2 shows that when this instruction in HCPNOS
executed, an unconditional data link will show the contents of register 11. Lines 3 through 9
define a conditional data link. Notice that in lines 6 and 8, spaces are used to improve
readability.
