When you specify a value in an ESL statement, the value is expected to be of the type required by that statement. However, if you specify a value of a type that is not expected in the statement, ESL attempts to convert this value to the type required by the statement. For example, suppose you specify:
move to A B
A and B are string variables; A has a value of "0" and B has a value of "200". ESL converts the string values "0" and "200" to the integer values 0 and 200, and then performs the move.
Type conversions are performed only on the following values:
Value |
Converts to |
Integer |
Floating point |
|
String |
Floating point |
Integer String |
String |
Integer Floating point Object identifier (name) with or without ancestry |
Boolean |
Integer Floating point String |
Object identifier (name) with or without ancestry |
String |
Other conversions are not performed by ESL. Conversions are never performed inside an expression. If you specify a value that cannot be converted to the required type, ESL produces an error message.
