here are some places to get information:
- help files
- script steps reference document you may download from FM Website
- functions reference document you may also download from FM Website
To download the documents, go to FileMaker Product Documentation | FileMaker , click on the link for your version and you will find the documents.
Do you have any past experience in programming ?
Agree with getting the Script and Function reference documents.
The pdf versions are great to search in (I keep copies on Dropbox). Up until FM 11 I used to print them out double-sided and bind them, they are very impressive documents. There is nothing like leafing through the pages and being able to make notes. I stopped only because they got too big to fit my comb binding machine.
What are you trying to achieve? Think of a script as a written set of steps which, if followed, will accomplish a specific task. A good way to start is to manually walk through the steps which will accomplish the desired task, writing down each step in a list. Once you have done that, open the script editor and convert you list of steps into the equivalent script commands.
