Syntax means the spelling, capitalization, spacing, and order of CALLBasic commands and any required parameters. The most seemingly popular mistakes are Case and parameter matching.
Some variables (and constants) are information you must supply. Other variables are placeholders for information that the system will return. Multiple commands can be placed in one script file, but only one command may be placed on a line.
CALLBasic is very particular as to the syntax & capitalization required. Make sure there is a carriage return at the end of each line (no spaces), you must have a carriage return after the EndProgram line, commands must be spelled correctly, have the right letters capitalized with the required parameters. Use sample scripts that are located in the CALLMaster Scripts folder.
