Re: Introducing delay in a assembler.
Nevertheless a word of explanation is indicated. It seems the opportunity for confusion arises from the double use of the equal sign. Without looking it up and entirely from memory, I could explain it as follows: The first equal sign is because BINTVL is a keyword operand of the STIMER macro - as opposed to REAL which is a positional operand. The second equal sign is a bit subtle. This is a use of an assembler facility, a literal, whereby a constant which requires to be defined in a storage area can be specified in the instruction where it is used. The constant in the form of a literal, which would otherwise appear as something like FIVESEC DC A(5*100) can be specified in a macro operand if, when used within the macro and extracted from that operand to create an instruction, it looks just the same as if the literal had been used on the instruction. I expect within the macro there is probably a load instruction and the second field of the instruction is the value of the BINTVL operand, for example L 1,=A(5*100) Where are those literals to be found? Well a tidy programmer - or one who needs to pay attention to addressing requirements in a largish program - will introduce a LTORG assembler statement somewhere in the sequence of instructions where constants will not get in the way, perhaps following an unconditional branch and typically near the end of a smallish source program module. If the programmer forgets I vaguely remember that the assembler has to tidy up for him/her by dealing with accumulated literals when the END statement is encountered. The constant could also have been defined as FIVESEC DC F'500' for example, but I think I adopted the A-form rather than the F-form of defining a full-word numerical constant because brackets printed more quickly than quotes on a 1403-N1 printer - what trivia one recalls! Personally, during my long career - my assembler class was in 1967 - with occasional bursts of assembler writing, quite early on I made myself a personal standard never to use literals since they led to untidiness. Also, talking about smallish and largish above in connection with assembler programs and standards I set myself, I decided that the sign of an assembler module which had become too large was one which could not be written with a single base register. In a sense these two standards cancelled each other out since, with the second standard, I could have happily used literals and let them be rolled out after the END statement without having to worry about exceeding the capacity of a single base register - most of the time! Come to think of it, there's another subtlety in the use of the asterisk for multiplication. Is it that the value corresponding to the BINTVL operand is in hundredths of a second so that specifying 5*100 emphasises this point, that is, it makes it clear that we want a 5 second delay? This is a calculation which the assembler does so that the value actually stored is 500. Chris Mason Normally, the Original Message from Gerhard Postpischil would appear here.

Introducing delay in a assembler.
Hi all, In my assembler program I need to introduce a wait or delay for 5 seconds. Is there any macro for doing it. I guess there is a WAIT macro but I dont know how to use it. Is WAIT macro intended for that purpose ? Even when I introduced the wait macro, I get a compilation error stating ECBLIST required. But I am not using any ECBs in my program and I don't have the knowledge of ECBs too. Please help me in this situation. All I need is very simple, in the middle of my program execution I need to introduce a WAIT of few seconds. How to acheive this.. Thanks in advance, Jerry. -- 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

WAIT specifically delays until an event is complete, as denoted by POSTing an ECB. ECBLIST is used to specify more than one ECB. For a simple delay, try: STIMER REAL,BINTVL==A(5*100) BINTVL specifies that the requested interval is in units of 1/100th of a second, so 5*100 gives you 5 second. Please note that you may be delayed for more than five seconds if your system is heavily loaded; the request only enables your program to run after five seconds, but does not guarantee that it will be dispatched.

Hi James, Thanks for ur reply.
