Copy of initial variable
copy_of_initial_variable
Description
Finds assignments from a local variable that is always initial
Extended Information
Reports DATA v TYPE ... [CLEAR v.] x = v. when all of the following hold:
* v is a local variable of a METHOD, FORM or FUNCTION, declared with DATA without VALUE, or with
DATA(v) = VALUE t( ). with an explicit type and nothing in the parentheses. Both make v initial, the latter
every time it is executed, so v is initial wherever it is read, also in loops
* v is never changed, except by CLEAR v., and its address is never taken
* v has exactly one read, the complete source of x = v., where x is not an inline declaration
* x and v are both reference types, or have identical types. Initial values convert differently between
types, e.g. an initial d becomes '00000000' in a string
* the declaration and the CLEARs are not chained
Objects with syntax errors, macros or unknown statements are skipped, as are procedures with dynamic code,
INCLUDE, test seams, enhancements or native SQL.
The quick fix deletes the declaration and the CLEARs, and replaces x = v. with CLEAR x.
No release requirement.
