C/iX *does* support default parameters in the middle of the function call
if the function is defined as an intrinsic with default parms.

Note that (unlike SPL and Pascal) tokens in C and in MPE/iX are normally
case sensitive.  The intrinsics defined in SYSINTR and declared in C/iX via
"#pragma intrinsic" are generally (always?) uppercase.  So, your call
should (assuming your parms are correct, as I didn't check) look like:

        HPSORTINIT( &sort_status,,,, sizeof(acct_info),, 1, keys );

This is all discussed in "HP C/iX Reference Manual" (06/92 edition, Reorder
# 31506-90005, Manufacturing Part # 31506-90011) in the 6 pages of Chapter
10, "Using Intrinsics".
