the question is clear as mud icon_cool.gif
but ...
generally IBM software is developed using ASSEMBLER or PL/X-390
( before that was PL/X-370 and before that was PL/AS and before that PL/S )
( an IBM internal use only HLL with a PL/I like syntax with additional clauses for REGISTER management and ASSEMBLER inlining with a pretty powerful MACRO language)

to see how a structure is coded in PL/xx
use ISPF to VIEW SYS1.MACLIB(CVT)

then enter the commands
EXCLUDE ALL
FIND '*' 1 ALL

scroll down until You see some PL/I like statements


the % stuff are macro/preprocessor stetements

good lurking


for a better examples do the same on SYS1.SAMPLIB(ACYCMS3A)
where You can see some register utilization directives and assembler inlining
