Answered my own question. This does what I need: DATA TEST1; SET TEST; STRING=COMPRESS(%NRSTR("%APPEND""("||COMPRESS(YEAR)||","||COMPRESS(CONDITION)||","|| COMPRESS(QRTS)||","|| COMPRESS(SAMPLE)||")"),""""); RUN; %APPEND can then be replaced by any macro name created, so this could be very useful. ...
Behaviour of null in Java
java,nullpointerexception,null,concatenation
String has a lot of special allowances in Java, for better or for worse. The specification dictates that null gets converted to the string "null" when converted to a string, e.g. by string concatenation (which implicitly calls toString() on other operands). So adding null to a string works by virtue...
Concatenating elements from two arrays of same indexes
To repeat the process for n elements in the array, you can do the following my @x=(1,2,3,4); my @y=(5,6,7,8); my @concatenated_array=(); for my $i (0 .. $n) # define $n <= min($#x,$#y) { push @concatenated_array, $x[$i] ."_". $y[$i]; } print "@concatenated_array\n"; ...
Is it possible to call a variable by concatenating two strings in JavaScript?
javascript,variables,concatenation
You could define the attributes as properties of objects and access them using strings, like this: var player = { str: 1, dex: 1, in: 1, ht: 1, strCP: 10, dexCP: 10, intCP: 10, htCP: 10, totalCP: 0 }, costs = { strCost: 10, dexCost: 10, inCost: 10, htCost: 10...
TypeError: cannot concatenate 'str' and '_sre.SRE_Match' objects
regex is not a string. It is a Match Object representing the match. You'll have to pull the matched text: fundleverage = "+" + regex.group(1) + "0" Note that your expression matches either a digit with a capital X or it matches a lowercase x (no digit). In your case...
Issues concatenating in Arrayfun with GPU processing. MATLAB
In this case, you can simply recast the whole problem as a multiple-right-hand-side call to \, like so: %# with A,B,C,D defined as per question AA = [10 11 ; 20 8 ; 30 30 ; 40 30]; x = [A(:)'; B(:)'; C(:)'; D(:)']; x1x2 = AA \ x; X1...
concatenating a uint8_t array into uint32_t array in C
If you really are working with decimal values: uint32_t dst[] = {1000000 * src[0] +10000 * src[1] + 100 * src[2] + src[3], 1000000 * src[4] +10000 * src[5] + 100 * src[6] + src[7]}; ...
SQL count date time
Yes you will need subquery: select * from (select someExpression as Requiredby FROM [dbo].[Main] where Location = 'Home' and ScriptTypeID = '1') t where Requiredby < GETDATE() But I really think you want this: select sum(case when cast(cast(DischargeDatenew as date) as datetime) + cast(DischargeTime as time) < getdate() then 1...
Concat Program, Weird symbols
The problem's here: //attach terminating null szTarget[targetIndex] = '/0'; The character literal should be '\0'. The notation's a backslash followed by one to three octal digits: that creates a character with the encoded value. char(0) == \0 is the ASCII NUL character used to delimited "C-style" aka ASCIIZ character strings....
What is the usage of adding an empty string in a javascript statement
javascript,string,concatenation
Type Casting. It converts the type to string If variable current.condition_field is not of string type, by adding '' at the end of it converts it to string. var field = current.condition_field + ''; So, field is always string. Thanks to @KJPrice: This is especially useful when you want to...
Is concatenation inside an ini file possible?
INI files does not allow you to include any logic, but you can do it by being tricky. Define upload_path as upload_path=root.path,tree.upload. Then in PHP read a value, and do some splitting: $parts = explode(",",$uploadPath); Now you will have and array that will look like this: ['root.path', 'tree.upload']. Now in...
Concatenate shows the second and third value except the first value
Edit: Added new code. It is hard to run the code as nobody but you has the workbook, and we would have to try and reproduce the workbook ourselves. Here is a revised code as I have interpreted what you are trying to do. I cannot test it as I...

How to console.log an object definition and a text in same string?
javascript,object,concatenation,console.log
console.log accepts any number of parameters, so just send each piece as its own param. That way you keep the formatting of the object in the console, and its all on one entry. var obj = { query: 'wordOfTheDay', title: 'Frog', url: '/img/picture.jpg' }; console.log( "Text Here", obj); // Text...
Numpy concatenate 2D arrays with 1D array
python,arrays,numpy,concatenation
Try concatenating X_Yscores[:, None] (or A[:, np.newaxis] as imaluengo suggests). This creates a 2D array out of a 1D array. Example: A = np.array([1, 2, 3]) print A.shape print A[:, None].shape Output: (3,) (3,1) ...
Should I use operator+= instead of operator+ for concatenating std::string?
c++,append,concatenation,stdstring
operator+= has the wrong kind of associativity for you to write code like your second example. For that to do what you want, you'd need to bracket it like so: (((myString += someString) += "text") += otherString) += "more text"; The alternative, which gives you the readability and efficiency you...
