I have a need to be able to call bpxwdyn from within an CA-Easytrieve "program".
According to the manual, IBM says that bpxwdyn can be called from non-REXX environments as long as certain rules are followed. It also states that values can be returned as long as the return value parameter follows the following format: PARMx DC Y(L'PARMxVAL+1) PARMxVAL DC C'parameter value ' (Notice the very important space at the end of the value string!) The manual states that the length must be 1 greater than the maximum length possible for the returned attribute. Since a dataset name can only be 44 bytes, the length value should be fine. My need it to call bpxwdyn and have it return to me the dataset name associated with a specific DD name. I have built the "command" string as follows: bpxwdyn-command DC Y(L'bpxwdyn-info) bpxwdyn-info DC C'INFO FI(MYDDN) ' I have built the information return parameter as follows: bpxwdyn-dsname-p DC Y(102) bpxwdyn-dsname DC CL100'INRTDSN ' The call in Easytrieve is CALL BPXWDYN USING (bpxwdyn-command, bpxwdyn-dsname-p) What's happening is that I getting a return code of 20, invalid parameter. What I don't get is whether it is with my command string or my returned value strings. The manual states that on a call from a non-REXX environment, R0 must be zero. According to the Easytrieve manual, the CALL verb generates an MVS convention calling list. So, based on that I can only assume that the last address in the parameter list has it's high order bit on. Also, have written several routines which trigger off of the number of parameters with the number of parameters signaled by the high order but of the last one being on, and having called these routines successfully in Easytrieve, I suspect my assumption is correct. What I don't know is whether Easytrieve sets R0 to zero for the call. If it doesn't, that could account for the return code of 20. So, my question is, has anyone ever called bpxwdyn from within an Easytrieve program?
