Set Column Names to UpperCase

wjalford — Tue, 26 Feb 2019 16:08:49 GMT

I am trying to set all the Column Names to uppercase. I have tried the below but it just changes the list to uppercase not the columns.

col_name_list = dt3 << get column names(string);
for (i = 1, i <= nitems(col_name_list), i++,
col_name_list[i] = uppercase(col_name_list[i]);

What do I need to do to change all of my column names to uppercase?

@wjalford ,

Try this ?

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );

CurrentCols = dt << Get Column Names("String"); 
Show(CurrentCols); 

for(i = 1, i <= N Items(CurrentCols) , i++,
	Column(dt,i) << Set Name(Uppercase(CurrentCols[i]));
   );

NewCols = dt << Get Column Names("String"); 

Show(NewCols);

You are going on the right track, the thing that you needed to add was the ability to set the column names in the table back to your new column names.
