This is all I could find: --- Bytes 288-295 contain the entry descriptor. EXTRACT STACKED STATE sets the condition code to indicate whether the entry-type code in the entry descriptor specifies a branch state entry or a program-call state entry. --- I can't very well issue ESTA looking at a dump. For BAKR and non- fastpath PC calls that create the linkage stack, the registers are stored in the USTA which also I can't find documented anywhere other than the aforementioned Share presentation. -- Don Poitras - SAS Development - SAS Institute Inc. - SAS Campus Drive [email protected] (919) 531-5637 Cary, NC 27513 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
