• A MAPPER Run lets you take the manual commands that you do frequently to develop a specific result, and create a program that will develop the same result, just by executing it.

• A MAPPER Run is a script, or a sequence of executable commands, stored in a report.– MAPPER runs are stored in the same kind of

reports as MAPPER data.

MAPPERMAPPER

MAPPER Run

5

• The Run Language or command set is an extension of the manual commands.

• In almost all cases there are run commands that are equivalent to the manual functions.

• There are many run commands that have no manual equivalent, mainly in the display and formatting of data.

• An example of a MAPPER run is the graphic commands. All of the chart commands are actually MAPPER runs. PCME is another example.

Run Language

6

• Find all the records in 2B0 where STCD = IP• Sort by CustCode• Match on ProductType, copy ProducCost from 1C0• Display the result

Run ExampleResults

8

• A run must be registered to execute– by the MAPPER Coordinator

• Runs can be registered for general use, or restricted.– Department– User-ID– Station– Time of day

MAPPERMAPPER

Run Registration

9

• The same run name can be registered for different departments or different people – and be something entirely different!– Point to 2 different scripts

• The same script report can be registered as multiple run names.– Internal logic governs behavior

@ LDV,W <time>s8=TIME$ . 09:13:44@ LDV <HR>s2=<time>(1-2),\ <MIN>s2=<time>(4-2),<Sec>i2=<time>(7-2) . Capture a reserved word value, split into 3 variables

@ LDV <Tyme>s6=<HR><Min><Sec> . Load a variable with TIME without colons. 091344

@ LDV <str>s32='Scott tiger Oracle database' .@ LDV <str>(7-5)='horse',<str>(13-0)='' .@ LDV <str>(0-3)='XyZ' . Load substrings. <str> variable now contains 'Scott horse XyZ'

MAPPERMAPPER

@LDV Load Variable

32

@ LDV,P <City>s24='BaNGAloRe' .

@ LDV,U <City>(1-1) LDV,O <City>(2-0) .

Variable contains unknown capitalization.

Upper-case the first character, and lower-case the rest of the string. Variable now contains 'Bangalore'.

MAPPERMAPPER

@LDV Load Variable

33

@ LDV V1s24='Roseville',V156i8=0 .

@ LDV,W V2=SOE$,V8s11=USER$ . • This is the old way of naming variables.

– Internally, BIS still uses this nomenclature.

• Variables are usually numbered up to V199, – May go higher if the run is registered for more variables.

• You should avoid using the two naming methods together in the same run.

MAPPERMAPPER

@LDV Load Variable

34

@ LDV V1i3=101,V2i3=102 .

@ LDV V99s32=VV1,V100s32=VV2 .

V99 is loaded with the value of V101

V100 is loaded with the value of V102

@ LDV,p <Var>s24='FirstName' .

@ LDV <<Var>>s32='Dave' .

Load the variable <FirstName> with 'Dave'

Storing a variable name within another variable is NOT a recommended technique, but you may occasionally see it used in specialized situations.

MAPPERMAPPER

@LDV Load Variable

35

@ LDA <color>s8[5]='Red','Blue','Yellow','Black','White' .

Load a 5-member array of colors, up to 8 chars each.

@ LDA <users>s32[15],<passwords>s32[15] .

Load 2 15-member arrays, up to 32 characters each.

@ LDV <users>[5]='Alpha',<passwords>[11]='Bravo' .

Assign values to the 5th user and 11th password.

Same options and variable types as @LDV

MAPPERMAPPER

@LDA Load Variable Array

36

@ LDV <counter>i4=1,<amt>i2=8 .

@ INC <counter> . Inc <counter> by 1

@ INC,2 <counter> . Inc <counter> by 2

@ INC,<amt> <counter> .

Increment <counter> by the value of <amt>.

@DEC works the same way to decrement the value of a variable.

MAPPERMAPPER

@INC Increment Variable

37

MAPPERMAPPER

@ART Arithmetic

@ ART 12+13;a/5;b*(a+3) <val1>i4,,<val3>i4 .

a = 25 stored in <val1> b = 5 not saved c = 140 stored in <val3>

38

@ DEF,,LIN+1 <len>i2,<value> GTO LIN+2 @ ldv <value>i4=1 .

Test if a variable <value> exists.If it does, use its value.If it does not, load a default value and use that.

Now we are guaranteed that the variable <value> exists and has a usable value.

MAPPERMAPPER

@DEF Properties of a Variable

39

@ DEF,p <len>i3,<string> .

@ LDV <LongString>(21–<len>)=<string>(p) .

Determine how long <string> would be if packed (leading & trailing spaces removed)

Load a longer string variable with the packed value of <string>, starting at position 21 for a length of <len>.

MAPPERMAPPER

@DEF Properties of a Variable

40

@ LCV,LIN+1 b3 <Path> '\' <pos>i3 . Find the 3rd backslash character in the <Path> variable.Go to LIN+1 if there is no 3rd backslash in the variable.

@ LCV,LIN+1 b99 <Path> '\' <pos>i3,<occ>i3 . Find the 99th backslash character in the <Path> variable.Most likely, there are not 99 backslash characters, so we go to LIN+1. The variable <occ> contains the number of backslash characters in <Path>.

@ LCV,LIN+1 b<occ> <Path> '\' <pos>i3 . Find the last backslash character in the <Path> variable, since now we know how many there are.

MAPPERMAPPER

@LCV Loc, Chg in a variable

41

@ LCV,LIN+1 t$ <txtFrom> ' '/'' . Remove any embedded spaces <txtFrom>

@ LCV,LIN+1 '' <string> 'Cat'/'Horse' . Change all occurrences of 'Cat' to 'Horse' in the variable <string>. Changing to a longer value works as long as there is room in the variable. If the new string is too long, it is truncated.

Exercise• Search report 2B0 for records where 'STCD' = IP.• Create a result containing a subset of each record.• Each line in the result should be of the format:

Product Type: value … Serial Number: value … Cust Code: value

• Display the new result.

• Do the same thing, but put 3 lines in the new result for each record in your search result:Product Type: valueSerial Number: valueCust Code: value

• HINT: you will need labels and a loop to do the second part, but not the first part.

• There are several commands that combine their operation with the update capability.

• These command will have a new call:– Search update is SU– Match update is MAU– Calculate update is CALU

MAPPERMAPPER

Update Commands

149

• First think of these commands as their original operation. For example, with Search we search for a specific string of information in a specific field or column. The result is a result containing only the lines of information the met the search criteria.

• Search Update works the same way, but now we can make a change to this result and have that change placed back into the original report.

• We could also delete these lines from the original report, or extract them out of the original report and create a new result containing just those lines.

MAPPERMAPPER

Update Commands

150

• Update (UPD) takes the current result on display and places information back in the original report.

• Delete (DEL) takes the current result and deletes it from the original report.

• Extract (EXT) takes the current result and deletes it from the original report and displays the deleted information as a result.

Exercise• Cabinet-Switch to remote BIS system.

(Instructor will supply details.)• Create a new report in the A0 drawer, and register

it as XXX using the REG command.• Write a run to:

– Connect to a relational database and retrieve data– Further process the data set using BIS functions

(Try to avoid SRH and SOR, since these are better accomplished with SQL WHERE and ORDER BY.)

• Use the RDI run as needed to test connectivity to the database, availability of tables, etc.

• Instructor will supply database, sign-on details.
