Thanks... I've used __asm with Windows C compilers, so I figured it
was available on the mainframe too, but I didn't want to say anything
since I didn't know for sure.
We use if extensively. You can use macros but in LE C need to create a
static function as there is no generate like Metal/C. For example.
double timeused() {
uint64_t mics = 0;
__asm(" IEABRCX DEFINE \n"
" TIMEUSED STORADR=%0,ECT=YES \n"
: "=m"(mics) : : "r0", "r1", "r14", "r15");
return (double)(mics >> 12) / 1000000;
}
static void generate_dsects(void) {
__asm(" CVT DSECT=YES\n"
" IHAECVT\n"
:
:
:
);
}
We have a common code #define for the "IEABRCX DEFINE" which is used in
all __asm() blocks. Check out Pete Relson's SHARE presentation for a
great reference to using __asm(). It's Metal/C focused but works the
same for LE C/C++

It certainly is possible using inline "__asm" blocks. Check out IBM's
