Has Jol kept pace?
o Does Jol generate JCL and write it to INTRDR? If not, how does it operate? o Does Jol provide the ENQ deadlock protection provided by batch initiators? o Does Jol provide flow control at least comparable to JCL's IF...THEN...ELSE...ENDIF? o Does Jol support tapes with facilities such as RETAIN and VOL=REF? o Can Jol's "card image" files have non-cardlike attributes such as RECFM=VB,LRECL=254 o Does Jol allow PARM length>100? o Does Jol support jobs with a mixture of steps running authorized and unauthorized programs, with the security of batch JCL? Most of these questions can be summarized as, "What facilities of today's JCL would the programmer sacrifice to gain the benefits of Jol?" -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
