Why you should care

[/vc_column_text][vc_column_text]While describing a PICTURE, once the length of a sequence exceeds 3 characters, use the factorized notation. Edition pictures (presence of Z) are not concerned.[/vc_column_text][vc_empty_space][/vc_column_inner][/vc_row_inner][vc_empty_space height=”12px”][vc_empty_space][vc_separator][vc_column_text]

How we detect

[/vc_column_text][vc_column_text]CAST Highlight counts one occurrence each time in the WORKING SECTION a PICTURE description not containing “Z” exceed sequences of more than three characters. In the following patterns, where sequences do not contain parentheses:

  • PIC <sequence 1>
  • PIC S<sequence 1>
  • PIC <sequence 1>V<sequence 2>
  • PIC S<sequence 1>V<sequence 2>

The length of <sequence 1> and <sequence 2> (if any) should not exceed 3 characters, excluding s if present.

Bad Code

PIC 9999
PIC 9999V9
PIC s9999V9
PIC XXXX

Good Code

PIC 9(4)
PIC 9(4)V9 
PIC s9(4)V9
PIC X(4)
PIC s999
PIC 9(7)V99999999999
