TECHNICAL CORRIGENDUM 2
Introduction
In the second paragraph, in the tenth sentence of bullet point “Intrinsic procedures and modules”, after
“C_F_POINTER” add “and C_F_PROCPOINTER”.
In the second paragraph, in the last sentence of bullet point “Program units and procedures”, after
“dummy argument” add “, or a coarray ultimate component of a dummy argument,”.
5.4.7
Append a new sentence to the second paragraph:
“If a coarray is an unsaved local variable of a recursive procedure, its corresponding
coarrays are the ones at the same depth of recursion of that procedure on each image.”
9.7.1.2
Delete the last sentence in the third paragraph, that is “If the coarray … on those images.”, and
insert the following three sentences:
“If the coarray is a dummy argument, the ultimate arguments (15.5.2.3) on those images
shall be corresponding coarrays. If the coarray is an ultimate component of a dummy
argument, the ultimate arguments on those images shall be declared with the same
name in the same scoping unit. If the coarray is an unsaved local variable of a recursive
procedure, the execution of the ALLOCATE statement shall be at the same depth of
recursion of that procedure on every active image in the current team.”
10.1.11
At the end of the sixth paragraph, add the sentence:
“If a specification inquiry depends on the type of an object of derived type, that type
shall be previously defined.”
11.1.7.2
In the first sentence of constraint C1128, after “of finalizable type,” insert “shall not have an
allocatable ultimate component,”
12.6.2.1
After constraint C1213 insert a new constraint:
“C1213a A SIZE= specifier shall not appear in a list-directed or namelist input
statement.”
13.7.2.3.3
In table 13.1:
change row 1, column 1 from “Ew.d” to “Ew.d with w > 0”;
change row 3, column 1 from “Ew.d E0” to “Ew.d E0 or E0.d”;

change row 4, column 1 from “Dw.d” to “Dw.d with w > 0”;
add new row 5 with cells:
column 1: “D0.d”
column 2: “any”
column 3: “D±z z z or E±z z z ”
1 2… s 1 2… s
13.7.2.3.4
In Table 13.2:
change row 1, column 1 from “ENw.d” to “ENw.d with w > 0”;
change row 3, column 1 from “ENw.d E0” to “ENw.d E0 or EN0.d”;
13.7.2.3.5
In Table 13.3:
change row 1, column 1 from “ESw.d” to “ESw.d with w > 0”;
change row 3, column 1 from “ESw.d E0” to “ESw.d E0 or ES0.d”;
15.4.3.4.2
In the final sentence of the first paragraph, after “(10.1.5)” insert “, treating a CLASS(*) dummy
argument as not differing in type or kind”.
15.5.2.11
In the second paragraph of the subclause delete the second and third sentences, that is “If the
dummy argument … array element order”. Insert a new (third) paragraph:
“If the dummy argument is not of type character with default or C character kind:
• if the actual argument is an array expression, the element sequence consists of the
elements in array element order;
• if the actual argument is an array element designator of a simply contiguous array, the
element sequence consists of that array element and each element that follows it in array
element order;
• otherwise, if the actual argument is scalar, the element sequence consists of that scalar.”
In the second bullet point of the third (now fourth) paragraph, after “substring designator”
insert “of a simply contiguous array”. In the third bullet point change “if the actual” to
“otherwise, if the actual” and delete “and not an array . designator”.
