So the common files are stored in MODE 2 FORM 1, the STR/XA files are stored in - MODE 2 and I've never seen any file stored in MODE 2 FORM 2. And the MODE 2 - FORM 1 and MODE 2 FORM 2 are also called XA-Mode1 and XA-Mode2 or simplier: - XA-1 and XA-2. + "MODE 2" but actually they are in MODE 2 FORM 2. The MOVCONV tool will + in fact produce files that does contain the subheaders. And those subheaders + seems to contain a CN equals to 1, and the flags RT and Data are activated. + + The last but not the least: the MODE 2 FORM 1 and MODE 2 FORM 2 are also + called XA-Mode1 and XA-Mode2 or simplier: XA-1 and XA-2. I hope this will help you as it helped me writing this software. |
