num-var = Has_Handle(line-ref)


Operands:

line-ref

A reference to a data line. The LineRef can be a numeric Line Pointer, or it can be a string containing a normal label (".ABC"), a pseudo-label (".123") or the string form of a Line Pointer ("!123"). A Line Handle name ("._123") cannot be used, nor can a Tag name(":ABC") be used.


Returns:


If the LineRef is a valid reference to a data line, and the data line currently has a Line Handle assigned to it, the function returns TRUE, and RC = 0. If the LineRef is valid but the line has no Line Handle, the function returns FALSE, and RC = 0, If the LineRef is an undefined label or refers to a non-existent data line or to a line that is not a data line, the function returns FALSE and RC has a non-zero value.


Special Notes


Unlike Get_Handle$, a call to Has_Handle only returns TRUE or FALSE, but does not create any new Line Handle if one is not currently present on the data line in question.
