Here my example I was referring to initially..
Execution JCL:
//REXXC JOB SYSTEMS,CLASS=A,MSGCLASS=X,
// MSGLEVEL=(1,1),REGION=4096K,NOTIFY=&SYSUID
//STEP1 EXEC PGM=TESTR1,PARM=('USER AA1122BB')
//STEPLIB DD DISP=SHR,DSN=SFORD.LINKLIB
//SYSEXEC DD DISP=SHR,DSN=IDF.CLISTLIB
//SYSTSPRT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SYSUDUMP DD SYSOUT=*
//SYSTSIN DD DUMMY
/*
-----------------------------
C Program
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
typedef struct IRXJCL_type
{
short int arg_length;
char argument[22];
} IRXJCL_type;
IRXJCL_type this_param;
IRXJCL_type* param_ptr;
main(int argc, char *argv[])
{
char dest[22];
int i = 1;
int s1;
memset(this_param.argument,'',sizeof(this_param.argument));
strcpy(dest,"IDFRACFC ");
strcat(dest,argv[1]);
strcat(dest," ");
strcat(dest,argv[2]);
strcat(dest," ");
strcpy(this_param.argument,dest);
puts(this_param.argument);
}
Output of Execution:

Without the memset in this example the C code fails. I am not the C heavy a lot
of folks are here,
but the ILC manual pretty much shows the same thing in examples going from C ->
Cobol -> C ..

What about
char *s6="wombat";
?
This makes s6 a pointer to the characters {'w','o','m','b','a','t','\0'}. There
is not really any difference between char s6[] and char *s6. You can still do
s6[0] which is the same as *s6. And s6[1] which is *(s6+1). s6[n] is just an
alternate way to say *(s6+n). Which is identical to *(n+s6). Which is identical
to n[s6]. As weird as that may be. I am not sure what C++ would do with that.
