I was doing some work to do with kdb and have been tinkering with strings and variables. I was just wondering if its possible to remove part of a string and add something to do the end of it.
s1:"Hello" s2:" World"
I have a joint string "Hello World" which I created using
s3:s1,s2
I was trying to remove the Hello and add something after the World in the joint string.
s3[1*til 6] = Hello
This allows me to select the Hello part of the string if this helps
you could use drop (_) to get rid of the "Hello" and join (,) to add on what you want. Something like
q)6_s3,"star Hiphop"
"Worldstar Hiphop"
If you didn't want to count the letters in the first word you could use vector from scalar (vs) to get a list of enlisted words and index into it, then join onto that:
q)(" " vs s3)[1],"star Hiphop"
"Worldstar Hiphop"
Hope this helps.
