RELATED IDEAS

Check/Reject when a variable A based on a pointer initialized with the addr of a variable B is bigger than B

See this idea on ideas.ibm.com


- a PLI V5.2 program runs smoothly but abends with S0C4 when recompiled in PLI V6.1
- on analysis, the program has a poor writing, it uses a larger redefined area than the original area. This original area is used as I/O area.

Presently, the compiler do make the check only if the too big variable is based on the addr of the small variable

Could you kindly add code to check that if

1) a pointer is assigned the address of a variable, i.e. p = addr(a)

2) and that pointer is specified as the basing pointer in the declare of another variable, dcl b based(p)


then if stg(a) < stg(b) issue a :

-W-level message, when the customer accepts a lax option

-E-level message, when the customer refused the lax option


Thank you in advance

    This will require some non-trivial work, but it would be very useful for many clients if we did this!
