|
|
* This command declares the names of fields <xField> (and <xFieldn> and

|
|
* This command allow Harbour to resolve any reference to a field
|
|
* specified in the field list by viewing it as a field when it is not
|
|
* referenced by an alias. If a field is not listed in this list and it
|
|
* is not explicity tagged with an alias indentifier, it may be viewed
|
|
* as a memory variable, which may cause run-time errors. This command
|
|
* has no effect on memory variables or on field reference buried within
|
|
* a macro expression.

|
|
* $DESCRIPTION$
|
|
* This command created a LOCAL memory variable or array. The name
|
|
* of either is specified in <xVar>. If more then one variable is being
|
|
* initialized with the LOCAL command,separate each entry with a comma.
|
|
* If a variable or an array is to be assingned a start-up value,that
|
|
* expression may be specified in <xInit> and folling. Is Strong type
|
|
* compile mode is used, the Compiler will check if the value recived
|
|
* matchs the type specified in <xType>.
|
|
*
|
|
* LOCAL varibles are symbols generated at run time and are resolved
|
|
* at compile time. The visibility and life span of a LOCAL variable or
|
|
* array is limited to the function or procedure in which it is defined.
|
|
*
|
|
* No macro expansions are allowed in the LOCAL declaration statement.
|
|
*
|
|
* No Harbour command other then FUNCTION, PROCEDURE, PUBLIC, PRIVATE,
|
|
* PARAMETERS, MEMVAR, STATIC and FIELD, may precede the LOCAL command.
|
|
*
|
|
* LOCAL array reference may not be initialized (i.e., assigned values)
|
|
* on the same command line as the LOCAL command statement. This can be
|
|
* done later in the program.
|
|
*
|
|
* LOCAL variables and arrays are not affected by the RELEASE command.

|
|
* This command tells the compiler to resolve any reference to a memory

* memory variable alias with either the M-> or MEMVAR-> prefix.Only
