Differences between Interactive COBOL 4.xx (4.60) 04-Jun-2012 and Interactive COBOL 3.xx 1. ICOBOL 4 allows both ICOBOL 3 format .cx files and ICOBOL 2 format .cx files to be run. While running ICOBOL 3 or 4 .cx files, ICOBOL 2 .cx files cannot be called from the same runtime process. While running ICOBOL 2 .cx files, ICOBOL 3 or 4 .cx files cannot be called from the same runtime process. 2. Under Windows, ICOBOL 4 provides only a single ThinClient, icrunrc, that provides both character and GUI support. Thus the thinclient will behave just like a thickclient runtime in that you can run both character and GUI executables. So there are no ICTHINS or ICTHINS executables. In the configuration file, the selection icthins, has been removed for @CON remote connections. In the Windows installer there is only one thinclient. All thinclients require an ICRUNRC license. 3. Under Windows, all runtime processes require a runtime license. In the past some runtimes did not "count" as a license. 4. System messages are preloaded by default thus not requiring a message file. If messages must be changed, ICMAKEMS can still be used to change then although with a new format. See the ICOBOL Utilites Manual. 5. Logged files must be converted to the new updated logging format via the ICLOG utility before they can be opened. 6. If upgrading from a revision before ICOBOL 3.30 all configuration files (.cf), printer translation files (.pt), and terminal description files (.td), have a new .ini based format. The extensions for these new file types are .cfi, .pti, and .tdi, respectively. The utility ICREVUP, has been provided to rev-up existing configuration, terminal description, and printer translation files to their new counterpart. ICREVUP Documentation --------------------- The basic syntax for this is: icrevup file.xx Where xx is .cf, .pt, or .td. ICREVUP will open the current file and output a corresponding file using the same PATH specifier as xxi. (I.E., cfi, pti, or tdi). These new files are used in the same places as the old files. The -h option can be used to view all of icrevup's switches. Under Windows, the install program will automatically rev up the specified .cf file when moving from pre-ICOBOL 3.30 to ICOBOL 4. NO OTHER FILES WILL BE UP-REVVED AUTOMATICALLY. All other files must be done by hand. One note in particular, the pre-3.30 .cf file had Master Console information that now resides ONLY in the pcwindow.tdi file. This information must be transferred manually. Under UNIX, NO files are rev'ed up automatically. All files must be rev'ed up by hand. The 4.00 ICCONFIG/ICEDCFW will ONLY work with the new .cfi, .pti, and .tdi files. If you wish to support older installations with .cf, .pt, or .td files then an older copy of ICCONFIG/ICEDCFW should be kept around to use for those installations until they are upgraded to 3.30 or greater.
