IC52128: HOD 9.06 VT CUSTOM FUNCTIONS NOT WORKING.

IBM Websphere Host On-Demand V10.0.3.0 Manufacturing Refresh

APAR status

• Closed as program error.

Error description

• Websphere Host On-Demand
  ------------------------
  Hod 9.06 VT custom functions not working.Customer defined
  functions with double bracket '[[' are now sending double
  brackets rather than single. If the customer modified the double
  bracket to single bracket then the custom function now works.
  

Local fix

• Modify the double bracket to single brackets and try the
  custom function.

  A method in HOD checks the first byte of the key sequence for
  an ESC, CSI or DCS sequence introducer. If it finds one of
  these it takes the entire string and sends it to the host all
  at once. This method was added to avoid sequences being sent
  one byte at a time.
  
  In this case the input sequence (custom VT function) has two
  left bracket '[' characters and both were being sent to the
  host in the string and it was not understood by the host.
  

Problem conclusion

• Added an extra check in PSVT.java, which scans the input
  sequence before it is sent to the host. If there is a double
  left bracket '[' character in the input sequence starting at
  the second byte then it will remove one '[' and shift the rest
  of the string to the left by one byte.
  

Temporary fix
