#delim looks very confusing to me. The normal usage is either #delim ; followed by commands terminated by semicolons, or #delim crfollowed by commands terminated by carriage returns. In the latter case, multi-line commands need to have the internal carriage returns commented out, eg by adding the string
\\\ to the end of every line except the last in every multi-line command.And are you sure that you have installed all the required packages (descsave, parmest, eclplot, sencode, fvregen, and keyby)?

With Stata 10 or below, you have to use -xi:- and -factext-.

Your code works like a charm, and is exactly what I needed. There have been some earlier queries regarding the ttest-parmby-metaparm task and I think you provided us with a perfect solution. I can now Eclplot all my test results with p-values as labels, great! Again, thank you for your help!

In a second step, I want to plot the means of the variables with CI's using ECLplot. I'm using Roger Newson's parmby, factext and metaparm commands. This is my code. I cannot manage to get factext working it seems, but I do not figure out where my mistake is. As is obvious, I'm not very experienced in programming Stata.
