Conversion Guides


CIAO 4.0 to CIAO 4.1

The major compatibility change in CIAO 4.1 is that ChIPS state files from CIAO 4.0 - i.e. the files created by save_state (S-Lang or Python help) and loaded by load_state (S-Lang or Python help) - can not be loaded into CIAO 4.1. Please contact the CXC Helpdesk if this is a problem for you.

Most ChIPS code written for CIAO 4.0 will continue to run in CIAO 4.1. However some code will need updating, as described in the upgrade guide.

The CXC provides help to users who need to update their CIAO 4.0 ChIPS scripts to CIAO 4.1.


CIAO 3.4 to CIAO 4.1

The CXC provides help to users who have CIAO 3 ChIPS scripts or code that they want converted to the new syntax (and capabilities) of ChIPS in CIAO 4.1.
