storage for vsam ext

Hi guys I know this is a well known problem but I don't find the right answer to fix it so may be you can give me a new idea. A very large program (cobol) with internal sort and using so many vsam files randomly fails when attempts to open a file because resource not available (status 93) or IE

Need simple example - Calling c subroutine like printf from HLASM program

I know that I've seen somebody do this before. But I cannot remember how they did it. Does anybody have a code snippet that shows how to call a C subroutine like sprintf() or strncmp() from HLASM? Also the compile & link JCL would be appreciated. I've tried reading the LE manuals and the C manua

Re: storage for vsam ext

Are you opening all files before you issue the SORT statement? Have you tried changing the sort storage parameters? The SORT-CORE-SIZE special register is the name of a binary data item that you can use to specify the number of bytes of storage available to the sortutility. It has t

Re: Need simple example - Calling c subroutine like printf from HLASM program

You want to make sure you are not creating and destroying a LE environment for every call, or it will get expensive. If your calling Assembler program is Language Environment-conforming, have a look in "z/OS V1R12.0 Language Environment Writing ILC Applications", section "14.5 Assembler Main Call

Re: Need simple example - Calling c subroutine like printf from HLASM program

You also want to be careful about the parameters. Some C routines expect values on the stack (i.e., in-line in the parameter list) and others expect pointers to the values with most using a mix. That is typically my problem calling or getting called from C: getting that sequence straight. Lloyd

Re: Need simple example - Calling c subroutine like printf from HLASM program

John, if you are playing with C subroutines and you don't need anything fancy from the C library, try out the METALC option of the C compiler. It generates HLASM code that you then assemble into a load module, so you get to see real assembler calling the METALC equivalents of the C library func

Re: Need simple example - Calling c subroutine like printf from HLASM program

Maybe it is just our C cross-platform code, but I have found that some parameters are by value and some by pointer in most routines. I have not tried to call printf, etc, as John asked about. For example, passing a input buffer with its length is typically pointer, value. Passing an output buffe

HLASM enhancement thought

This is just a thought that I had. I'd appreciate feedback about its utility. HLASM currently can do some tests on symbols, such at "type" (T'SYMBOL) or "length" (L'SYMBOL) and others. I thought it might be useful to have another test to see if the symbol can be resolved via as "relative" operan

Re: HLASM enhancement thought

An interesting idea, but there are a couple of potential problems: (1) Addresses and offsets aren't known until the end of the first pass over the source, when the values of all symbols are known. This means it's difficult to capture the needed information in time for use by conditional assembly.
