Why is this an issue?
Moving a large string into a small field will result in data truncation with data lost from the right side of the string.
Noncompliant code example
01 ALPHA PIC X(4).
MOVE "Now is the time" TO ALPHA *> Noncompliant. Becomes "Now "
01 ALPHA PIC X(15).
MOVE "Now is the time" TO ALPHA
- S1967 - for truncation of numeric values
