Script Syntax Requirements

The STN Express Script Language has few general syntax requirements. However, each statement has its own syntax.

  • More than one statement may appear on the same line, or each statement may be typed on its own line.

  • The keywords in the Script Language are not case-sensitive. For example, the EXIT statement may be written EXIT or exit.

  • Upper- and lowercase are significant in character strings. For example, "Yes" is different from "yes".

  • Blank lines may appear anywhere.

  • Blanks and space characters may appear anywhere. However, they are significant in strings (inside double quotes). For example, "STNExpress" is different from "STN Express".

  • A line in a script is limited to 80 characters, but a single script statement can be 140 characters long.  To continue a statement on the next line, put a backslash, \, at the end of each line that is continued on the next line.

  • Enclose strings in double quotes.

  • Comments are notes that describe or explain the script, and they are ignored by the script processor. Comments begin with \* and continue until the end of the line. Comments may appear on lines of their own, or they may appear at the end of any statement except the Prompt Statement.

  • STN commands can be up to 256 characters in length.
