Arguments in ZeoScript are delimited by spaces. Hence, any string argument that contains a space will be split into separate strings. To prevent string splitting, you should surround your string in “quotation marks”. Here is an example:
project.SaveProjectAs "C:\\temp\\this is a temp project name.proj"
Two strings may be concatenated together using the strcat function. More strings may be added by nesting calls to strcat, as below:
// create a new string for name
string MyName
// allow user to edit name
EditUI &MyName "Please enter your name"
// add strings together ("Hello " + MyName + "!"), and echo to screen
echo <strcat "Hello " <strcat MyName "!">>
The output of this script is:
Hello Aaron!
The length of a string may be determined using the strlen function, as demonstrated below: 
string s int i // initialise a string set s "This text is 31 characters long" // get the text length using 'strlen' set i <strlen s> // report the text length echo i
The output of this script is:
31
