You can access and run its functions as soon as the package is properly integrated into your z/OS and/or TSO/E environment. The following steps are required to install the Alternate Library: (1.) Unzip ALTLIBZOS.ZIP in a temporary directory on the PC Edit the extracted "ftpput.cmd" file. This file looks like: uid password quote site LRECL=80 quote site RECFM=FB binary put MAKEALT.CNTL '#hlq.REXX.MAKEALT.CNTL' ascii put MAKEALT.README '#hlq.REXX.MAKEALT.README' quit Change the userID value (uid), password value (password) and all '#hlq' values accordingly. Save and close "ftpput.cmd" Open a DOS Window and call the following command: ftp -s:ftpput.cmd *hostname* *hostname* is the name of your HOST system. To connect your PC to a HOST you have to know the full qualifier of your HOST system, e.g. "mysystem.mydomain.com" It contains the following files: o JCL job MAKEALT to build the load module o A REXX compiled object file that is used for functional verification o This README file with the latest information (4.) Upload (as text FB 80) the JCL job MAKEALT. (5.) Customize the JCL job MAKEALT. It contains predefined predefined steps to automate the installation and verification. It does the necessary copy steps to: (a.) Create the object library <#hlq>.REXX.ALT140.OBJECT (b.) Assemble and link-edit steps to create the load library <#hlq>.REXX.ALT140.LOAD (c.) Create the REXX verification module VALTLIB. You must customize the PROC section as follows: (a.) Replace the first qualifier <#hlq> by the appropriate high-level qualifier (b.) The JCL MAKEALT includes a job step to allocate the object library <#hlq>.REXX.ALT140.OBJECT (c.) The JCL MAKEALT includes a job step to allocate the load library <#hlq>.REXX.ALT140.LOAD (d.) If desired specify the load data set that you have already allocated, and comment or discard the entire job step ALLOLOAD (e.) The load library <#hlq>.REXX.ALT140.LOAD has record format U, record length 0, block size 23200 (6.) Contents of the load library after successful link-edit Name I Alias-of I Size ----------I------------I------------ EAGKCPT 00000058 EAGRTALT 00005F80 EAGRTPRC EAGRTALT 00005F80 EAGRTPRQ EAGRTALT 00005F80 EAGRTXIN EAGRTALT 00005F80 EAGRTXLD EAGRTALT 00005F80 EAGRTXTR EAGRTALT 00005F80 EAGRTXVH EAGRTALT 00005F80 IRXCMPTM EAGKCPT 00000058 VALTLIB 000019C0 (7.) Verify the Job output listing for all return codes that are zero. The output of the verification REXX exec is listed at the bottom. It mainly contains the return values of the Parse Source and Parse Version statements. The Alternate Library uses the System Product Interpreter. The REXX "Parse Version ..." statement returns REXX370, whereas the REXX Runtime Library Version is REXXC370. This is the expected output of the Verification step: * ---------------------------------------------------- * REXX Source: TSO COMMAND ? ? ? ? MVS MVS ? SPI Version: REXX370 3.48 01 May 1992 OK, I was executed by the Alternate Library * ---------------------------------------------------- * 3.0 USAGE CONSIDERATIONS ------------------------- The Alternate Library is shipped together with the fee-charged program product 569501403 for z/OS. It is designed for REXX developers who want to distribute REXX compiled products. IBM grants you to package the Alternate Library to your REXX compiled products. That is why customers who do not own the 569501403 REXX Library can run REXX compiled code. Note, however, that the Alternate Library has almost no benefits compared to the "real" REXX Runtime Library. This package enables users to install the Alternate Library in their system in a fast and easy way. Vendors who distribute REXX compiled code may want to add this package to their installation. 4.0 NOTICES ------------ This information was developed for products and services offered in the U.S.A.
