Create a testcase
All testcases delivered electronically to IBM must be in a compressed format.
MVS customers should use the TRSMAIN program to compress their file [PACK parameter]. The program and instructions can be obtained from the IBM web site http://techsupport.services.ibm.com/390/trsmain.html.
By compressing the data, you improve data transfer time and convert your file into a familiar record length and format. To meet additional security issues it is possible to encrypt the testcase.
Notes: To prevent problems with special MVS data (like e.G. SMF data, GDG's etc.), please see : ftp://ftp.ecurep.ibm.com/pub/mvs/docs/ECuRepMVS-SpecialData.pdf
