Large syntax files in IBM SPSS Statistics very slow to navigate
Troubleshooting
Problem
I am using IBM SPSS Statistics. I have a syntax file that is over 1 MB in size. When I open the file, I can see the syntax commands but SPSS seems to hang and I am not able to navigate within it. After a couple minutes, I can them move about in my file. What is happening?
Symptom
large syntax file. hang on opening. slow to navigate
Cause
This behavior is a combination of the large file and having all the options enabled for the syntax window. SPSS is loading all this information on launch of the file, hence the inability to click.
Resolving The Problem
This behavior is a combination of the large file and having all the options enabled for the syntax window. SPSS is loading all this information on launch of the file, hence the inability to click. To speed up the load time, launch SPSS and go into Edit->options and click the Syntax Editor tab. Uncheck the options that are unnecessary for you, for example Display Color Coding. Click Apply and OK. Now you will be able to navigate the large syntax file sooner without the long delay.

Hi @Roger Fiedler 

This question has come up many many times over the life of IBM SPSS Statistics (and before it "SPSS for Windows").  As the product has progressed through the years the Syntax Editor has. become less and less like a text editor.  It is constantly checking key presses and revising the display.  With longer command syntax files, it reaches a point where interactivity is seriously degraded or lost entirely. At that point, I usually direct the user to the above technote. The sum of that technote is to make the IBM SPSS Statistics Syntax Editor as much like a text editor as possible.

If your command syntax file is still so large that it is unwieldy in the Syntax Editor, then there really are only two solutions that remain:

• Actually take the syntax into your favorite text editor.
• Break the syntax up in thematic modules and then knit the modules together as needed using INSERT command syntax from a main syntax file.  Better still to make use of Python Programmability to control these underlying modules of command syntax.
