Language Constructs & Functions
Language Constructs & Functions Overview
Functions take one or more comma-separated parameters and return a result. The
following template shows how each language construct and function is explained.
Name:
The name used to refer to the construct or function.
Syntax:
The SIMPL+ specific language requirements for this particular construct or function.
This section demonstrates exactly how to enter the statement in a SIMPL+ program.
For completeness, the general syntax for SIMPL+ functions is shown below:
<Return Value Type> FunctionName(<Parameter 1 Type> [,
<Parameter 2 Type> ...]);
The Types are described as STRING, INTEGER, LONG_INTEGER,
SIGNED_INTEGER, and SIGNED_LONG_INTEGER.
If a STRING is specified as a return type, a STRING or STRING_OUTPUT variable
may be used.
If an INTEGER or LONG_INTEGER is specified as a return type, an INTEGER,
LONG_INTEGER, ANALOG_OUTPUT or DIGITAL_OUTPUT may be used.
If a STRING is specified as a parameter, a STRING, STRING_INPUT,
BUFFER_INPUT or literal string (i.e. “Hello””) may be used.
If an INTEGER, LONG_INTEGER, SIGNED_INTEGER or
SIGNED_LONG_INTEGER is specified as a parameter, an INTEGER,
LONG_INTEGER, ANALOG_INPUT, ANALOG_OUTPUT, DIGITAL_INPUT
or DIGITAL_OUTPUT may be used. A literal integer (i.e. 100) may also be used.
Note that for DIGITAL_OUTPUT values, a value of 0 is equivalent to digital low,
and any other value is a digital high.
Description:
General overview of what this function does.
Parameters (applies to functions only):
Specifics on each of the parameters listed.
