Re: Submit a program call

Back again... I tried out both Elvis' and Barbara's (I hope a first name
basis is ok!) solutions but I can't even get a compile:

"A parameter of type "main_args_t *" cannot be initialized with an
expression of type "char **"."

After taking a closer look at the language ref manual it seems as though one
*has* to pass char **? Just seems so incredibly awkward that I, just to
perform a simple SBMJOB on the call to this program, would need to go
through a CL program and manually append null terminators etc... (which is
what they do in the Programmer's guide when calling C from CL).

all would be fine.

Any better solutions than having the program called via SBMJOB to have a
main function and then manually typecast the parms from argv's char * to
their proper ones (say integers)?

If the parameters aren't all the same type, the argv parameter doesn't
have to be coded as an array. It can be coded as a pointer to a struct
with pointer subfields of the required type. (Don't forget the
"program-name" subfield for argv[0].)

typedef struct
{
char *pgmname;
char *userid;
char *code;
int *custno;
} main_args_t;

main (int argc, main_args_t *main_args)
{
char *userid = main_args->userid;
char code = *main_args->code;
int custno = *main_args->custno;

}
