LabTalk Improvements

LabTalk Callable OC function to Execute an Operation

(ORG-7877)

Click on the recalculate lock and select Show Info from the context menu to get the "operation_uid", then run execute_operation function.

execute_operation(operation_uid);

Improve LabTalk "type -gb" command for text file output

(ORG-8306)

type -gb [[e][f][r/n]] fileName;

New line is \r\n by default, n = use \n as new line, r = use \r as new line.  

Better error checking in LabTalk function

(ORG-9155)

In an OGS file, add the following script, and then run the main section, the error message will go to Message Log.

[Main]
Function int aa(int nn)
{
	ty "inside function";
	sdf;//error
	return 1;
}

int nErr = aa(0);
ty "after function";

LT access to user color increment list

(ORG-8942)

LabTalk can now get or set in the same command area as set/get data plot colors. The syntax is:

set %C -cue bval;  //set custom list enable
get %C -cue bval;  //get custom list enable

Sample:

newbook;
col(A) = data(1,12);
col(B) = col(A);
plotxy (1,2);
set %c -ci 1;
set %c -cue 1;
set %c -cu 2 4 6 8;
dataset ds;
get %c -cu ds;

Labtalk Function to Generate Patterned Data

(ORG-7900)

• To generate numeric data:

col(A)=pattern(1,10,2,2,3); // from, to, inc, value repeat count, sequence repeat count

• To generate string data:

stringarray sa;
sa.Add("NY");
sa.Add("MA");
col(B)=pattern(sa, 2, 3); // string sources, value repeat count, sequence repeat count
//can also allow quoted string separated by pipe, comma, or space
col(B)=pattern("NY|MA", 2, 3);
col(B)=pattern("NY,MA", 2, 3);
col(B)=pattern("NY MA", 2, 3);

• To generate pattern data based on a column:

col(B)=pattern(col(c), 2, 3); //data source, value repeat count, sequence repeat count
col(B)=uniform(30, col(A)); //randomly choose 30 elements from col(A) to fill col(B)

Range Notation Improvements

• Support Variables for Row Subrange Notation:

int a = 1;
int b = 12;
range rr=col(1)[a:b];

• Option Swich to Define a Temporary Vector for Storage And Assignment of a Block of Data:

//Import a sample data into a new book
fname$=system.path.program$ + "\Samples\Matrix Conversion and Gridding\DirectXY.dat"; 
newbook;
impasc;
//Define the first row (from column B to E) as the first block
range -v r1=B[1]:E[1];
//Define the first column (from row 2 to 6) as the second block
range -v r2=A[2:6];
//Assign the values in the first block to the second block
r2=r1;

• Support Range Declaration for Local Loose Dataset:

dataset ds1,ds2; 
range rngld1=[??]!ds1;
range rngld2=[??]!ds2[10:15];  
range aa=1!1, bb=2[10:15];  //Given col(a)&col(b) is filled with row numbers: 
rngld1=aa;
rngld2=bb;

• preserve double quotes:

range r1 = 1!; //First sheet in the activated workbook
range r2 = "1!"; //Column with long name "1!"

Substitution Notation Improvement 

(ORG-9221)

Layer (command) Supports Subrange

range rr = wcol(2)[ 1:10 ];
win -t plot;
layer -i rr; // Plot rows 1 to 10

New System Variables

New LT Objects/Properties/Methods

Provide Tooltip for any object with Script, Run After set – We will hide it in 9.1

(ORG-8882)

For button in Graph or Worksheet with script behind it, if you set @GSB=1, when mousing over the button, tooltip will tell you how to view/edit script and how to delete the object.

LT command to list number of DataRange 

(ORG-7522)

Running script "list rng;" takes quite a long time to finish the listing. The following command will output the number of DataRange directly.

doc.rangescount()=; /// all ranges
doc.rangescount(16)=; /// all empty ranges
doc.rangescount(32)=; /// all "AutoFill" ranges
