Both LMINIT and ALLOC map a DSNname to a Dataid. Can I use a Alloc in my Program and then use LMOPEN directly. In other words the mapping between the DSNname and the Dataid, which the Alloc and the LMINIT does, are they same and can they be used interchangebly. If not, Please explain me the difference between the two.
Similarly can somebody explain me what is the difference between LISTDSI and LISTDS.
Thanks a lot. |

First of all, please read this sticky note at the top of the CLIST & REXX Forum. You seem to be confused about what is REXX, what is TSO, and what is ISPF.

No. The TSO ALLOCATE Command allocates a dataset and optionally assigns it to a DDNAME for subsequent use by a program.
The LMINIT ISPF Service allows the dialog to associate a data ID with a specified ISPF library, concatenation of ISPF libraries or MVS partitioned data sets, or an MVS partitioned or sequential data set. The data ID is generated by LMINIT and can be used to identify the data set for processing by other library access services or the BROWSE or EDIT service.

The TSO LISTDS Command is used to have the attributes of specific data sets displayed at your terminal.
The LISTDSI REXX (or CLIST) Function retrieves information about a data set's allocation, protection, and directory and stores it in specific variables. |

Hello,
When i try to get syscreate info thru LISTDSI command a gdg version, the result is blank though RC is 0.
Find below the code.
| Code: |
say $name
dsinfo = listdsi("'$name'")
say rc
IF RC = 0 then
SAY SYSCREATE
else
say "file not found"
$name is T6201BTX.T6201.DAILY.HANG.G1403V00. |
output is
T6201BTX.T6201.DAILY.HANG.G1403V00
0
// here i should have got syscreate result. but it
// is blank
Is there any restriction on getting syscreate info for a gdg version? |

Try this change first:
| Code: |
...
say $name
rc = listdsi("'$name'")
say rc
if rc = 0 then say SYSCREATE
else say SYSREASON
