Summary: Microsoft COBOL Version 3.00 or 3.00a can create and use threads by calling API (Applications Program Interface) routines in MS OS/2 protected mode. The following example demonstrates how to create an MS OS/2 thread: 1. Compile the first thread as follows: PCOBOL THREAD1; 2. Link the first thread as follows: LINK THREAD1 /NOP,,,PCOBOL+DOSCALLS; 3. Compile the second thread as follows: PCOBOL THREAD2; 4. Create a .DEF file. 5. Create the Dynamic Link Library as follows: LINK THREAD2 /NOP,,,PCOBOL+DOSCALLS,THREAD2.DEF; 6. Move the new THREAD2.DLL to a directory specified by the LIBPATH= variable that resides in the CONFIG.SYS or CONFIG.OS2 file. 7. Run the threads by executing THREAD1.EXE.
More Information: A source code example of the above can be found in the Software/Data Library in the file COBTHRED by searching on the keyword COBTHRED, the Q number of this article, or S12102. COBTHRED was archived using the PKware file-compression utility.
