Why you should care

For code readability purpose, avoid initializations with 0 or spaces.

CAST Highlight counts one occurrence each time one of the following patterns are encountered in the WORKING STORAGE section:

  • VALUE 0
  • VALUE +0
  • VALUE ‘ ‘ (string containing only blanks)
  • PIC X(<length>) VALUE ‘<string>’, where the length of <string> is different from <length>
  • MOVE 0
  • MOVE +0
  • MOVE ‘ ‘
