== Why is this an issue?

When using ``++CICS XCTL++`` or ``++CICS LINK++``, it is a bad practice not to specify the length of the communication area.


=== Noncompliant code example

[source,cobol]
----
  EXEC CICS LINK PROGRAM ('SPI2TCV') COMMAREA (SPI-PARMCICS)  RESP (WS-RESP)  *> Noncompliant

  EXEC CICS XCTL PROGRAM ('P4DERROR') COMMAREA (Y4DERROR)  *> Noncompliant
----


=== Compliant solution

[source,cobol]
----
  EXEC CICS LINK PROGRAM ('SPI2TCV') COMMAREA (SPI-PARMCICS) LENGTH (SPI-LONG) RESP (WS-RESP)

  EXEC CICS XCTL PROGRAM ('P4DERROR') COMMAREA (Y4DERROR) LENGTH (Y4FLFIC-Y4DERROR)
