Construct Errors (Compiler Errors 1600 to 1608)
Compiler Error 1600
construct error: 'Function Main' cannot contain function
parameters
'Function Main' cannot return a value
Function Main is the starting point of a SIMPL+ program. It is automatically called
once when the system startup or is reset. Since this function is invoked by a method
outside of the SIMPL+ module, no arguments can be included in it’s argument list
and no value can be returned from it.
The following are examples of this error:
Function Main() // ok
{
}
INTEGER_FUNCTION Main() // error – Main() cannot
return
// a value
{
}
Function Main( INTEGER cmdLineArg ) // error – Main() cannot
contain
// a parameter list
{
}
Compiler Error 1601
construct error: DuplicateCASE Statement
Constant expected: '<identifier>'
Unlike the Switch Statement the CSwitch statement’s case statements must consist of
unique values. Expressions are not permitted within the case statements. Instead,
each case statement must contain a unique integer value for the CSwitch’s
comparison.
The following are examples of this error:
FUNCTION MyFunc( INTEGER x )
{
STRING str[100];
CSwitch( x )
{
case (1): // ok – 1 has not been used yet
{
}
case (2): // ok – 2 has not been used yet
