Re: Need help with ISPF Dialogue Manager and VGET
Keep in mind that if you do VDEFINE(s), you MUST do VDELETE(s) for the same variables, before you FREEMAIN (e.g.) and/or exit. Otherwise, enjoy tracking down mysterious S0C4s, etc. ISPF will think that the storage is still allocated to the function pool variable(s) and may read from or write to it/them. To clarify what was already said, you don't need VDEFINE if your assembler program is not interacting with the data. For example, if you are displaying a panel that, implicitly or explicitly, does all needed VGETs, VPUTs and operations for some variables, no VDEFINEs are needed for those variables. If you are only inspecting or setting a particular variable once, VCOPY or VREPLACE will do just as well, without the need for VDELETE. Less clear cut is when a program is invoked by SELECT. It would seems that all function pool variables are deleted, along with their reference addresses, lengths, etc. I'm not sure; YMMV. That said, unless you are writing a program product (and maybe even then), you are better off using ISPEXEC from assembler. It is easier to write and maintain, and also offers variable substitution: CALL ISPEXEC,(BUFLEN25,BUFFER25),VL ... Buffer25 dc c'display panel(abc&xyz)' Buflen25 dc a(l'Buffer) In fact, this could all be nicely packaged into an assembler MACRO. Compiled REXX, CLIST (see note), and the Pipes/ISPF stages will give you better performance than interpreted REXX, without the productivity downsides of assembler. (AFAIK, ISPF has it's own internal copy of the CLIST interpreter that loads and/or runs faster than the usual CLIST interpreter; call a CLIST only via SELECT.) ISPF dialogs with only ISPLINK require lots of extra coding, more detailed knowledge of the business requirements, perfect comments for future victims, and full understanding of dialog services. Finally, the TSO variable lookup routine IKJCV441 can only get or set once variable at a time. With TBxxx services this is a burden; a requirement to address this was never approved. I hope this helps. On Thu, 2 Aug 2018, 1:04 pm Seymour J Metz, wrote: > When last I had access to ISPF I used them heavily.

Re: Need help with ISPF Dialogue Manager and VGET
OK, I'll bite... Beverly, What is your point? That Paul didn't know something, asked a question, and yet appears to actually have a decent grasp on the subject? Is that somehow offensive to you, or are you just stirring the pot for no reason here? Seriously: I'm all for appropriate snarkiness. Those who have bothered to read my posts here will at times have argued (silently or otherwise) with the appropriateness of that snark. But I don't think I have ever responded as you did to someone who seems to have done nothing the least bit provocative. Perhaps you can give some clarification of the goal of your post; perhaps I have totally misinterpreted the tone, in which case I apologize in advance. If you *were *intending to be rude, like, stop it. This is a professional forum; we have some fun, we have some rogues who take the occasional jab, we have folks whose social skills seem to result in rudeness when it later appears none was intended. Those are all different from just causing trouble for the sake of causing trouble. On Wed, Aug 1, 2018 at 2:42 PM, Beverly Caldwell wrote: > Well, you are almost there, Paul.

Need help with ISPF Dialogue Manager and VGET
Hello, . I need some clarification on using the ISPF VGET Service in an Assembler Program, the examples I've found were not much help. . . I have a CLIST which issues a VPUT for three Fields Name, City, STATE. These variable are placed on the SHARED POOL. The CLIST then invokes an Assembler Program which should issue a VGET for the three variables and write them to a VSAM dataset. . In the examples I found I never see the Variables for the VGET defined in the program. . I suspect I need to first issue a VDEFINE, with a Name List, Variable list, Format List and Length List prior to issuing the VGET. . THE VGET SERVICE only identifies a name-list like NAME-LIST EQU * DC A(3) DC A(0) DC CL8'NAME ' DC CL8'CITY ' DC CL8'STATE' . Do I need to issue a VDEFINE first for the Variables specified in the VGET. Would someone please clarify . .
