Hi there,
It would be my great pleasure if anyone could assist me with the following error, caused after I applied strrep to more than 32 substrings:

If you make x a string array with 96 or more elements, then the entire code can be replaced with
%{
newIDFFile = regexprep(readIDFFile, '@@P(\d+)@@', '${x{str2double($1)}}')
%}
For example,
x = "Here!"+(1:96);
readIDFFile = 'hello @@P3@@, how are you? @@P48@@ says hi!';
newIDFFile = regexprep(readIDFFile, '@@P(\d+)@@', '${x{str2double($1)}}')
newIDFFile = 'hello Here!3, how are you? Here!48 says hi!'
