Referencing an object from its name

fromname()

Reference an object from its name

SYNTAX

fromname(object_name)

References an object from an alphanumeric field or text string containing the object’s name.

Parsing the name at run time is a relatively slow operation, so if more than one reference is to be made, it is recommended that a pointer is assigned to the object, as in the example below.

Since Sculptor 6.2.0:

• Supports nested records and records with dimensions.

• The subscripts can be other field values (no need to be literal values any more), like fromname("fldArray[fldNumber]").

EXAMPLE

!temp PrintFuncPtr,,p
!temp PrintFuncName,,a20
!temp PrintMode,,a1

     if (NormalPF->checked = TRUE) then PrintMode = "N"
     if (CompPF->checked = TRUE) then PrintMode = "C"
     if (LongPF->checked = TRUE) then PrintMode = "L"

!report PrintDD {
     ...

     FieldNo = 1

     while (FieldNo <= tmp.NumFields) {
          PrintFuncName = "PrintField" / PrintMode
          PrintFuncPtr = &fromname(PrintFuncName)
          PrintFuncPtr()
          FieldNo ++
     }
}

!function PrintFieldN() {
     statements
}

!function PrintFieldC() {
     statements
}

!function PrintFieldL() {
     statements
}

Example with a nested record array:

!record Rec1[2] {
    !record SubRec[4] {
        num,,i4[10]
    }
}

ptr =& fromname("Rec1[2].SubRec[3].num[ Rec1[2].SubRec[5].num[1] ]")
