> 27998, the non-spanned maximum blocksize for 3390 devices, That's the optimal block size, not the maximum.

Go figger.) Updated to: It would be useful is the current limit would be raised to a higher value, and tentative maximum values could be 27998, the non-spanned maximum blocksize for 3390 devices, or 32767, the maximum signed value for a halfword, but even a value of 1024 or 4096 would be more helpful. -- Robert AH Prins robert.ah.prins(a)gmail.com The hitchhiking grandfather - https://secure-web.cisco.com/1fY3ETqcBDtdts-bgTZ0S5I_14qCzzpAZKfw3_Gba59WiK7MGnssYQeMul8XMxP8D4dcu7aFntnq5B5CUj7g7Vj8aUdKGUMlVaE14Z1rAmvS8ONbiPNPF6UYobmu2RQZWtYF67blTRVef9heKeb0xGcLEN2FP2OxzKM1X0hThQiw5xrD0oPIw4jmFg90In-RajqU3ENBFXKBgriYBMWjyLnRgBy6IHZPT_TV_R5EJoVQ5bFA8ddk1y5yYE6EJp4f4tRKsU2WrIWRQMrJNXQW6YwI61Wx1PYehGsC2Vljzoz6N5AFT-TbSOwlSK4nK8L5jN1G2qBZ342_U2Y0EbUWplk4EgKa8N2Rwede5Ibvjov8FeiaEIvZ8r4HRyYRPMCDlTYEpedxUsImiL1vMk_YdZGQJC0Ufm4DZbyfUjtX3h9HQPsHU5kIs_nBKX86ASXu5/https%3A%2F%2Fprino.neocities.org%2F Some REXX code for use on z/OS - https://secure-web.cisco.com/1NkflYZPw5LPHXVnfhyLDydnTvPNfnGd8Rwy3AA-n1MLZi6UzIQnU1aQjpZyMmYPwux1QSpugP657-ul-xYfsho3g3r6OyTbShjD-vPhgYgpXyvfBfHFqEQoTQbIj_bytA3evLjclDXzL7XOyf9VwH4MeACGMIZMfS_pgMgAzUqGvhlW-iOGi9Hu7UmPte33g2MAhA2DPI2tCMiLtQDlHfPkUhaenS_txOjLX3U0pwtIpo_qtu4ASIe-XNHTir5-E4Mk5dtpOBZOoJDWTNkN8AREeHBrsMZKLQdy89Kl_rekVCM2wJ-2AKNnFkWKgvj6vZqlDN0-mruJSkM-0sGYOJMZBWKY6ABca5kpBPOj1liCWE4GkS6mYtlLObfRmRCZdMC8FLTiC66N3iFQaHNMSgsDpDeJRcMGW2QskT-Sw-dLBg9yqSH3iaKkGCTedq23t/https%3A%2F%2Fprino.neocities.org%2FzOS%2FzOS-Tools.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
