True, but there are other utilities that support the ISPF convention. At least using the convention lets you play well with them.

While those ENQs protect against simultaneous updates by multiple ISPF users, they do not protect against updates by other non-ISPF programs, such as IEBCOPY, IEBGENER, or many others. Using SPFEDIT ENQs in Zowe would have the same strengths and weaknesses as using those ENQs in ISPF. An ENQ convention can only truly be relied upon if all users of the system follow that convention. SPFEDIT falls short in that. -- Regards, Gord Tomlin Action Software International (a division of Mazda Computer Corporation) Tel: (905) 470-7113, Fax: (905) 470-6507 Support: https://secure-web.cisco.com/1wk_fK40tJnD49IlqpTSbT2kUgOFyxuko28zeIHXYway4_mk797YUHZxS9sqYkWiMwg9Lhc61tC4vhYcKlJoERKldbJMTmPbkLh2D2CleyI6hPZu7evyo8rnODdq6NQCWkq4KObJICHhCNUJVCq6zCSFri-lhpnnRTJuhY6ivXe6gQjWmsc8SCfjrtuIZUrzzjVYvByB5uGQOrLt5srKdSgaXYLVs_P9loOB48h3ATMrr7UDZ7TZcyJSbY92JZYvQRAVuI_XvD2JnyAv-aCtTMTSQYoHtv48Jj7PI4kKyOAAnhJOWNgq-SROIgHxP5t0MWvAMfiBrkYT29nwfXKhbwHTTfCOxNvBearweo11APh921e1XScVcUt2Vs6tg-5OVi5JJji0YB5s1tByxgB7xde_B0a84yEFratVJXlVGiwAKjO4yKY3P377GPuM8EIzp/https%3A%2F%2Factionsoftware.com%2Fsupport%2F ---------------------------------------------------------------------- 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
