Another example of TSSL 0.6 code to test syntax highlighting:

#!/usr/bin/env TsslInterpreter
!TooSimpleScriptingLanguage 0.6

# Print text and a new line character(s), LF or CR+LF
print line> Welcome here! It's a demo program that tests the 0.6 update of TSSL!
# An empty line
print line>

@ask
# Print text as it is (without beginning a new line)
print> [whoami/greet/exit]:
# Read user input and save it to the value (variable) named "option"
ask line> option
# If user input equals "whoami", jump to the "print_user" label
<print_user ?equals> \{option};whoami
# If user input equals "greet", jump to the "greet" label
<greet ?equals> \{option};greet
# If user input equals "exit", jump to the "end" label
<end ?equals> \{option};exit
# Otherwise, ask for input again (jump back to the "ask" label)
<ask

@print_user
# Run the "whoami" command and pause execution of the script until it finishes
execute wait> whoami
# If whoami ran successfully (did not exit with 0), ask for input again
<ask ?equals> \{_last_execute_status};0
# If it returned a non-zero code, let user know
print line> An error occurred.
# And only then ask for input
<ask

@greet
print> Your name:
ask line> name
print line> \{name}, hi!
<ask

@end
