Yves, On our z/OS V2R4 system, ISPFHTML does not fail and works as advertised.
You pointed out that upon entry, R1 contains the address of a TLD (Terminal Logical Descriptor) which is the ISPF control block associated with each logical screen under ISPF. On my system, ISPFHTML code shortly after entry does a BAL to x'184' into the TLD, where on my system this code fragment resides: 58F09190 L R15,X'190(,R9) 07FF BR R15 58E0 9194 L R14,X'194(,R9) 07FE BR R14 00030858 In the TLD Yves displayed from his system, at x'184' offset there is this, instead of the code above: D4C1C3D9 which is c'MACR', not code. The TLD no longer holds code at that offset, but character strings. Doug used to work in ISPF development at IBM. His code is using knowledge he had of the TLD format that us mere mortals don't have. Looks like the TLD may have changed under z/OS V3R1? Mike Shaw MVS/QuickRef Support Group Chicago-Soft, Ltd.
