In other words, you changed your ESQL to 5.X, right? This makes creating
ESQL/C customized Ace/Perform runners impossible.

Did you try reinstalling the old products from original media?

This could be because you have the parameters backwards.

Here's your problem. The third parm is supposed to be your tag name.
col_name should be the *first* parm, and you need a field tagged "bob"
in the form.

This works using the demo with 4.1 ESQL/C and 4.16 ISQL:
(bob.ec)
#include "ctools.h"
/* #include "acct.h" */
$include sqlca;
valueptr bob();
$ int id_num;
$ char col_name[7];
/**********************************************************************
ALL functions must be listed here!
*****************************/
struct ufunc userfuncs[] =
{
"bob", bob,
0,0
};
valueptr bob()
{
pf_getval("lc",col_name, CCHARTYPE,8);
strcpy(col_name, "status");
pf_putval(col_name, CCHARTYPE,"bob");
}
(bob.per)
DATABASE stores
SCREEN
{
------------------------------------------------------------------------------
ORDER FORM
------------------------------------------------------------------------------
Customer Number:[f000 ] Contact Name:[lc ][f002 ]
Output from bob:[bob ]
}
TABLES
customer
ATTRIBUTES
f000 = customer.customer_num;
lc = customer.fname;
f002 = customer.lname;
bob = customer.address1;
INSTRUCTIONS
after editadd editupdate of fname
call bob()
end
