But a good conjecture (that or something similar) on the OP's problem.

If so, no, that sounds wrong to me. > It's documented that if a count is specified, that number of lines is written from STEM. If count is given as "*", writing terminates at the first null member of STEM. Now, I'll conjecture: If the member has ISPF statistics, it was probably created by ISPF EDIT, and ISPF will never write an empty record. If the member lacks ISPF statistics, it was probably created other than by ISPF EDIT and may contain empty members. The write will terminate at the first empty line. Bad design. It would be better, when count is "*" to write until a DROPped line of STEM. is encountered. What happens if STEM.0 exceeds the number of defined lines of the compound? What happens if count is "*", but a DROPed line is encountered before an empty line? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
