The problem is that ISPF/ISREDIT evaluates/substitutes any ISPF variable, which
in this case is "&PDQR".
So:
ISREDIT F ALL 'DISP=SHR,DSN=MSYS.UCMD.REMOTE' "
is the same as
"ISREDIT F ALL 'DISP=SHR,DSN=MSYS.UCMD.REMOTE&PDQR' "
and is the same as
"ISREDIT F ALL 'DISP=SHR,DSN=MSYS.UCMD.REMOTE&PDQR.' "
In the latter two cases (apparently) "&PDQR" resolves into "" (empty) and
"&PDQR." also. (The dot "." is used as an end-of-variable-name marker, IIRC.)
In e g this:
"ISREDIT F ALL 'DISP=SHR,DSN=MSYS.UCMD.REMOTE&PDQR.(' "
- resolves to: "ISREDIT F ALL 'DISP=SHR,DSN=MSYS.UCMD.REMOTE(' "
wich is no to be found in the dataset.
Etc.

Thomas Berg
