Yves,, IMHO (and I am only a lowly bit fiddler with VSE background)
the problem is this code in ISPFHTM 47F0F026 B OVER_EYECATCHER 21C9E2D7 C6C8E3D4 D340F0F0 F0F2F040 6040C2C1 E2C540D6 E261F3F9 *.00..ISPFHTML 00020 - BASE OS/39* 0976F020 F040D94B F1F0 OVER_EYECATCHER DS 0H 90EC D00C STM 14,12,12(13) 5890 1000 L 9,0(,1) <-------1 45E0 9184 BAL 14,x'184'(,9) <-------2 see the line with the <----1 either this receives the wrong value in R1 or the line with the <-----2 has the wrong offset for the jump/BAL onto where r9 points now without a little comment/hint, we have no idee what ISPFHTML expected.... to me this looks like someone called ISPFHTML with the wrong parms.
