Number Of Columns In An Array?

[mawright89]

Is there a script which retuns the number of columns in an array... am using a 2D array with one row, but need to determine the number of columns with values and set a variable to that value. Any ideas on how to do this?

Cheers

Sure: numcols()

There are three functions, one for each possible dimension:

numrows()

numcols()

numdepth()

Thanks, can I pass a string from one position lets say;

leakspools[0][3]

into the;

beginseq()

function to start a sequence if the text in the array is named the same as the sequence? I cant seem to get it to work. I am using another variable to set the position of the array data to be extracted;

beginseq(leakspools[a])

Should this be working?

You can't pass any parameters to a sequence when starting it with beginseq(). You'd have to use a global variable to somehow get it to the sequence. You could pass it as a function of course, but then it runs in the same thread as the calling script:

myFunc(leakspool[a])

[mawright89]

thats fine, whats the script for running as a function?

function.leaktest(leakspools[a])

is that close?

[mawright89]

lets put this another way i think im confusing myself;

testorder[testnumber] returns the name of the script to be run.

can I use that to start the script of the same name or does it not work like that?

One last thing, Im logging values to an array for writing to a .CSV file, how do i change the number of significant figures shown after the decimal point. currently at 6 and dont need that many.

Lots of questions here:

1) to call as a function, its simply:

leaktest(leakspools[a])

You don't do "function." in front.

2) if you have the function name you want to call in a string variable, you have to build up the script as a string then use execute():

execute(testorder[testnumber] + "(leakspools[a])")

3) changing the sig figs depends on how you are logging. In logging / export sets there is a column labelled "Figs". For writeDelim() you'd have to create an array of strings instead of an array of numbers and put the formatted numbers into that array of strings. It might be faster to actually format the entire row into a 1 dimensional array of strings, or simply as a string and write it that way. WriteDelim() itself doesn't give an sig fig options.
