To load the data from a *.SEQ file to your mainframe system: The * used in this document is the name of your file i.e. JCL (JCL.SEQ) or VSAM (VSAM.SEQ). 1). Transmit the file SEQTOPDS.TSO to a sequential dataset named: youruserid.SEQTOPDS.EXEC. Note: Use CRLF and ASCII (text file convert to EBCDIC). 2). Transmit the *.SEQ to a sequential dataset named: youruserid.*.SEQ. Note: Use CRLF and ASCII (text file convert to EBCDIC). 3). Logon to TSO (using youruserid) and enter the following TSO command: EX SEQTOPDS EXEC 4). For the first prompt, enter: *.SEQ For the second prompt, enter: *.LIB For the third prompt, enter a valid generic unit name for your shop (eg. SYSDA). For the fourth prompt, enter a valid volume name for your shop, if required. For the fifth prompt, enter: RECFM(F,B),LRECL(80),BLKSIZE(27920) or other suitable TSO ALLOCATE DCB, if required. This should create a PDS named: youruserid.*.LIB. 5). Student userid's must be granted read access to this dataset to browse examples and solutions.
