Introducing Suprtool/UX Version 4.4 * Highlights * Known Problems * Compatibility * CPU Serial Number (uname) * Documentation * Documentation in WinHelp Format Use Suprtool/UX to read, select, and sort data from Oracle and Allbase databases and from data files with fixed-length records. Suprtool/UX is designed to be similar to Suprtool for MPE while providing necessary HP-UX features. Suprlink/UX provides high-speed data-file linking based on a sort key. Use STExport to convert fields in a self-describing input file into an output file that can be imported into different applications. Highlights * Suprtool now supports string expressions in both the Extract and If commands. String expressions allow users to select and format their byte-type data in numerous new ways. This includes combining byte-type fields together, upshifting and downshifting data, and trimming blanks. These new features combine to reduce the number of tasks needed to select and format the data the way you need it. * Suprtool now supports 5,100 bytes of constants to be extracted. (only NM and HP-UX) * Suprtool, Suprlink and STExport now have the ability to create their own persistent redo stacks. The contents of these stacks can be recalled not only in the current session, but also in a future session. Known Problems There are no known problems at this time. Compatibility Suprtool/UX is compatible with HP-UX 9.0, all versions of HP-UX 10.x, as well as Oracle version 7.1.3.2.0. On HP-UX 10.x, Suprtool/UX creates all of its temporary and scratch files in /var/tmp, unless the temporary directory has been overridden with the TMPDIR environment variable. Suprtool for HP-UX typically comes with two versions in two different directories on your tape. The version of Suprtool in /opt/robelle is compatible with HP-UX 10.20 and later. The version of Suprtool in /usr/robelle is compatible with versions earlier than HP-UX 10.20. Suprtool will no longer save an output file when no records have been written and an error has occurred. CPU Serial Number (uname) This program runs only on CPUs whose serial numbers have been encoded (the "uname" on HP-UX). If it fails to run and you get an "invalid HPSUSAN" error message, call Robelle for assistance. Documentation The user manuals for Suprtool and its components are available on-line. You can access these files from within Suprtool by simply typing the Help command. We also distribute all three user manuals as a Windows Help file. If you are already familiar with Suprtool, you can access only the Suprtool/UX topics that are different from those of Suprtool/MPE. The "Running" section of the Help file has been updated for Suprtool/UX. You can access it with the following Help command: >help running Documentation in WinHelp Format The user manuals for Suprtool and its components are all available in the WinHelp file format of Microsoft Windows. Your tape includes a WinHelp file, which is a self-extracting compressed file that contains all the Help files and a Setup program. Use the installation instructions in this change notice to install the WinHelp files on your PC. Installation of 4.4 The following instructions describe the installation process of a new Suprtool release. The new version overwrites the existing version of Suprtool on your HP-UX system. Who Should Use These Instructions? The system manager should use the following instructions to install Suprtool/UX. During the installation, which should take only a few minutes, no one can use Suprtool/UX. Summary of Installation Steps To install Suprtool, follow these steps: 1. Log in as root. 2. Create the correct directory structure. 3. Restore Suprtool/UX and its associated files from the distribution tape. 4. Set up variables to let Suprtool know where its supporting files are located. 5. Install WinHelp documentation files. (optional) Installation Assistance If you have any questions about the upgrade process or run into any problems, please call us. Technical support is available on weekdays from 7 a.m. to 4 p.m. Pacific time at 1.888.robelle (1.888.762.3553). Step 1: Log In as Root There are two ways you can log in as root: a. Exit from HP-UX and log in with root as the user name. b. If you are already logged in, you can execute this command: su - In either case, you have to know and supply the user password for root. Step 2: Create Robelle Directory Before restoring files, you must first create the directory where Suprtool/UX will reside: mkdir /opt/robelle Step 3: Restore Files Use the following command to restore the Suprtool/UX files from the distribution tape: tar xv /opt/robelle This command assumes your tape device is /dev/rmt/0m. If it is not, you need to specify your tape device using the "f" option in the tar command. For example, if your tape device is /dev/rmt/1m, you need to use the following command to restore the files: tar xvf /dev/rmt/1m /opt/robelle Step 4: Set the ROBELLE Variable You must set the ROBELLE environment variable so that Suprtool can find its Help and Suprmgr files. Bourne and Korn Shells export ROBELLE=/opt/robelle C Shell setenv ROBELLE /opt/robelle Step 5: Install WinHelp Documentation Files (optional) The Suprtool documentation for both MPE and HP-UX is now available in the WinHelp file format of Microsoft Windows. To install the WinHelp files on a PC, follow these instructions. Make a Temporary Directory for the Setup Program From either DOS or Windows Explorer, make a directory into which you can copy the installation files. For example, at the DOS prompt type mkdir \robtemp You can remove this directory after installing the WinHelp files. Download the Compressed File Use Reflection to download the self-extracting Zip file to your PC and continue with these steps. This Zip file on the HP 9000 is /opt/robelle/winhelp/suprhelp.exe . From the /opt/robelle/winhelp directory, press Alt-Y to go to the Reflection Command Line window. Then use the following command to download the file using a binary transfer: receive c:\robtemp\suprhelp.exe from /opt/robelle/winhelp/suprhelp.exe binary Expand the Compressed Files You only need the following commands to extract the files, because we provide both the Setup program and the Help files in one self-extracting Zip file. From the DOS prompt, type the following commands: cd \robtemp {go to the new Robtemp directory} suprhelp.exe {extract the Help files} Run the Setup Program To run the Setup program, select the Run command from the Start menu. When the Run window appears, enter C:\robtemp\setup in the Command Line window and follow the instructions in the Setup program. When the Setup program ends, you can access all of the Suprtool documentation by selecting any of the icons in the "Robelle Help" Program Manager Group. Remove the Robtemp Directory Before you remove the WinHelp files, you can copy them to a diskette or a CD and distribute them to other Suprtool users. To delete all the WinHelp files and remove the Robtemp directory, use either the Windows Explorer or the following DOS commands: cd \robtemp del *.* {delete all the files in Robtemp} cd .. rmdir robtemp {remove the Robtemp directory} Enhancements Every year we provide Suprtool/UX users with new features. The following section describes the new enhancements to Suprtool since the last major release. Extracting Constants Previously Suprtool was limited to 1,530 bytes of constants for MPE/iX and HP-UX versions of Suprtool. This limit has now been increased to 5,100 bytes. The MPE/V version of Suprtool is still limited to 1,275 bytes. Persistent Redo Commands entered at the Suprtool prompt are saved in something called the redo stack. You can recall commands from this stack by using other commands such as Before, Do and Redo. By default, the redo stack is stored in a temporary file and discarded as soon as you exit Suprtool. This temporary stack is not preserved across Suprtool invocations. The new Set Redo command assigns a permanent file as the redo stack, allowing the stack to become available for future Suprtool invocations. For example, to assign the myredo file to a persistent redo stack, enter >set redo myredo If the file does not exist, Suprtool creates it. Otherwise, Suprtool uses the existing file. All subsequent commands are written to the persistent redo stack. This setting is valid for the duration of the Suprtool session. As soon as you exit Suprtool, the setting is discarded. Next time you run Suprtool, you will get the temporary stack. If the file name is not qualified, the redo stack is created in the current working directory. This may be desirable if you want to have separate stacks. If you want to always use the same persistent stacks, you should qualify the name. The Verify command shows which stack is currently in use. If it shows <temporary>, it means Suprtool is using the default stack. Anything else is the name of the file used on the Set Redo command. Concurrency When Suprtool uses the default temporary stack, it is accessible only to that particular instance of Suprtool. You can run as many Suprtool instances as you need and each one gets its own redo stack. With temporary stacks, you will never have concurrency problems. If you start using a persistent redo stack, however, you might start running into concurrency problems. A persistent redo stack can be used by only one Suprtool instance at a time. If you try to use a persistent redo stack that is already in use, you will get the following message: >set redo myredo The redo file is already in use. Unable to open file for REDO stack In this situation, Suprtool continues to use the redo stack active at the time and lets you continue working as normal. Qedit can also have permanent redo stacks. To prevent products from writing to each other's redo stack, it is advisable to use separate stacks for each product by giving them different file names. For example if you use >set redo myredo you will have a redo stack called myredo for your Suprtool commands. If you exit Suprtool, then run Qedit and supply the same Set Redo command, your Qedit commands will be written to the same file that was used for your Suprtool commands. String Expressions Both the Extract and If commands have been enhanced to allow string expressions, which can be used to: 1. Combine two fields together (using the + operator). 2. Remove spaces (using the built-in trim functions). 3. Upshift or downshift characters. String expressions reduce the number of tasks required for many common operations involving byte-type fields. Fewer tasks means that Suprtool delivers data to your applications faster than ever before. These changes are so extensive that string expressions are described separately for the Extract and If Commands. See the sections below for specific details and examples of string expressions. Extract Command You can now use string expressions in the Extract command. String expressions allow you to combine byte-type fields together (using the + operator) or operate on byte-type fields with special functions. In many cases, you can now reduce the number of tasks required to format the data the way you want. Fewer tasks means that Suprtool delivers the data where you need it faster than ever before. To extract a string expression, use this syntax: EXTRACT target-field = expression Target-Field The target-field determines the byte-length for the expression. The data-type must be Byte or Char. The expression is extracted during the output phase and cannot be used by other Suprtool commands that accept fields (e.g., Sort). Examples >extract id-no = warehouse-no + bin-no >extract full-name = first-name + last-name Constants vs. Expressions If you have an string expression that starts with a string, Suprtool assumes that you are attempting to extract a single string value and not a string expression. To specify a string expression that starts with a constant, surround the expression with parentheses. For example, Incorrect >extract name = " " + product-desc Error: Missing comma or invalid arithmetic expression Correct >extract name = (" " + product-desc) Variable Length Strings String expressions use variable-length strings. Suprtool keeps track of the length of every string, and all operations are done using the actual string length. For fields, the length of the string is the length of the field. If you do not want to retain all of the spaces in a field, use one of the built-in trimming functions. String constants are created with the exact length of the constant. For example, the string "abc" is three characters long and the string "a" is one. When assigning the string expression to the target field, Suprtool pads the final string value with spaces to fill out the target field. String expressions longer than the target field generate an error. >in testfile >def a,1,10,byte >ext a="I'm too long for this container" Error: String is too long for the specified item String Truncation Suprtool produces an error if the string expression is longer than the target field. You cannot override this error with Set Ignore On. To help avoid the error, you may want to trim trailing spaces from the expression before assigning it to the target field. For example, >extract new-field = $trim(a + b + c) Upshifting Strings ($Upper) Use the built-in function $upper to upshift all of the characters of a string expression into uppercase characters. This function can be used to upshift a single field, a complicated string expression, or any subpart of an expression. Both ASCII and Roman-8 characters are upshifted by $upper. For example, >extract city-up = $upper(city) >extract full-name = $upper(first + last) >extract desc = desc-1 + $upper(desc-2) Downshifting Strings ($Lower) If you want to downshift all characters of a string expression to lowercase, use the built-in function $lower. This function can be used to downshift a single field, a complicated string expression, or any subpart of an expression. Both ASCII and Roman-8 characters are downshifted by $lower. For example, >extract city-lower-case = $lower(city) >extract city-state = $lower(city + state) >extract desc = desc-1 + $lower(desc-2) Trimming Spaces ($Trim, $Ltrim, $Rtrim) Use one of three built-in string functions to remove leading or trailing spaces from a string expression. The three functions are: $Trim: Remove leading and trailing spaces from the string expression. $Ltrim: Remove leading spaces. $Rtrim: Remove trailing spaces. If Command You can do comparisons with byte-type fields in numerous ways using Suprtool. These powerful features minimize the number of tasks you must execute in order to select the data you need. The fewer the number of tasks, the faster your data is delivered to the users and applications that need it. You can combine byte-type fields together and use the built-in string functions to create string expressions. String expressions involve the + operator and any of the built-in string functions, which are $lower, $upper, $trim, $ltrim and $rtrim. Fixed vs. Variable Length Strings String comparisons are done using fixed- and variable-length strings. For most users, there should be no difference between the two types of strings. When doing string comparisons, Suprtool always pads shorter strings with spaces, with the one exception of comparing two fixed-length fields (see "Byte Fields" below). String expressions involving the + operator or the $lower, $upper, $trim, $ltrim and $rtrim built-in functions are done using variable-length strings. Suprtool keeps track of the length of every string, and all operations are done using the actual string length. For fields, the length of the string is the length of the field. If you do not want to retain all the spaces in a field, use one of the built-in trimming functions. When creating string expressions, string constants are created with the exact length of the constant. For example, the string "abc" is three characters long and the string "a" is one. Byte Fields For historical reasons, comparing two byte-type fields to each other is a special case. If the two fields are exactly the same length, Suprtool compares them completely. If one field is shorter, the comparison is done for the length of the shortest field. Suprtool does not check for spaces in the trailing characters of the longer field. For example, >define short, 1,10 {10-character field} >define long ,11,15 {15-character field} >if short = long In this example, Suprtool compares the 10 bytes in the short field with the first 10 bytes of the long field, but ignores the last five bytes of the long field. If the expression on either side of the equal sign consisted of more than one field (using the + operator) or involved any of the built-in string functions, such as $lower, $upper, $trim, $ltrim and $rtrim, Suprtool would have compared both sides of the equal sign by padding the shorter field with spaces. It is only the case where you are directly comparing one byte-type field to another that Suprtool uses the length of the shortest field for the comparison. Trimming Spaces ($Trim, $Ltrim, $Rtrim) Use one of three built-in string functions to remove leading or trailing spaces from a string expression. The three functions are: $Trim: Remove leading and trailing spaces from the string expression. $Ltrim: Remove leading spaces. $Rtrim: Remove trailing spaces. Because Suprtool pads shorter strings with spaces when doing comparisons, trimming spaces is most useful when creating a combined string with several fields. For example, you might want to combine a person's first and last name (including a space between the two): >if $trim(first) + " " + $trim(last) = "Joe Smith" Mixed Case ($Upper and $Lower) By default, Suprtool does an exact match when comparing two string expressions. If the expressions vary in the capitalization of characters, Suprtool will find them unequal. To do caseless string comparisons or pattern matches, use the $upper or $lower functions. Both ASCII and Roman-8 characters are shifted by $upper and $lower. For example, >if $upper(city) = "VANCOUVER" >if $lower(city) = "edmonton" Note that if you use the $upper or $lower functions, Suprtool does not shift any constants in the comparison. You must explicitly specify the constants in the correct case or you can use $upper or $lower with the constant: >if $upper(city) = $upper("vancouver") Use the $upper or $lower functions for caseless pattern matching. As with other comparison operators, you must specify constants in the correct case when doing pattern matching: >if $upper(city) == "VAN " >if $lower(city) == "ed " You can use $upper and $lower with string expressions that combine many fields and string functions. In the following example, we create >if $read - $upper($trim(first) + - " " + - $trim(last)) - = "JOE SMITH" - Bugs Fixed Add Command. The Add command no longer fails in the following cases: 1. Extracting byte-type fields with constants and the literal string values are shorter than the length of the field. 2. A self-describing file with more than one field is used as input. Arithmetic Operations. Suprtool now has a better error message when an arithmetic operation has an invalid decimal operand length. Extract Command. When extracting constants, Suprtool no longer incorrectly reports that the constant limit has been reached. Extract Command. When extracting one field into another, invalid data is no longer produced if the two fields are exactly the same length and type, but have a different number of implied decimal places. Extract Command. When the maximum limit of extracted constants is reached, Suprtool no longer incorrectly reports the following message: Error: Number of constants in >EXTRACT exceeds maximum This error message has now been changed to: Error: Total size of constants in >EXTRACT exceeds maximum Set Ignore On. Suprtool now honors the Set Ignore On flag when encountering an illegal packed decimal number in the $stddate function.
