I am trying to split strings.
In global scope it works :
arg:“abc def”
i:arg?" "
value “0 “,string[i],” _ arg”
Output
(“abc”;" def")
However in function scope
{i:x?" “; value"0 “,string[i],” _ x”} [arg]
I get the error message x
Question:
How to make value execute in function scope
value doesn’t work in function scope because it is looking for the global variable x;
q)x:arg
q){i:x?" “; value"0 “,string[i],” _ x”} [arg]
“abc”
" def"
However, there is a better way to do this using vs (vector from scalar):
q)arg
“abc def”
q)" " vs arg
“abc”
“def”
The evaluation of value does not see local variables in the function. Why not simply use a function for this purpose?
{(0;x?" ")_ x} arg
Or if the original problem is, as stated, to split a string, use vs
q)" " vs “abc def”
“abc”
“def”
