Logical AL intrinsics

Equal (any a1, a2) result logical

Return true if a1 is equal to a2.

Equal (any list l1, l2) result logical

Return true if list l1 is equal in size, order and element-by-element to list l2.

Unequal (any a1, a2) result logical

Return true if a1 is unequal to a2.

Unequal (any list l1, l2) result logical

Return true if list l1 is unequal in size, order or element-by-element to list l2.

Not (logical b) result logical

Return logical 'not' of b.

And (logical b1, b2) result logical

Return logical 'and' of b1 and b2. Both b1 and b2 are always evaluated.

Or (logical b1, b2) result logical

Return logical 'or' of b1 and b2. Both b1 and b2 are always evaluated.

Less_equal (integer i1, i2) result logical

Return i1<=i2.

Less_equal (real r1, r2) result logical

Return r1<=r2.

Less_equal (sequence s1, s2) result logical

Return true if s1 is before or equal to s2 in the sequence.

Less_equal (string s1, s2) result logical

Return lexical s1<=s2, where trailing blanks are significant.

Less (integer i1, i2) result logical

Return i1<i2.

Less (real r1, r2) result logical

Return r1<r2.

Less (sequence s1, s2) result logical

Return true if s1 is before s2 in the sequence.

Less (string s1, s2) result logical

Return lexical s1<s2, where trailing blanks are significant.

Greater_equal (integer i1, i2) result logical

Return i1>=i2.

Greater_equal (real r1, r2) result logical

Return r1>=r2.

Greater_equal (sequence s1, s2) result logical

Return true if s1 is after or equal to s2 in the sequence.

Greater_equal (string s1, s2) result logical

Return lexical s1>=s2, where trailing blanks are significant.

Greater (integer i1, i2) result logical

Return i1>i2.

Greater (real r1, r2) result logical

Return r1>r2.

Greater (sequence s1, s2) result logical

Return true if s1 is after s2 in the sequence.

Greater (string s1, s2) result logical

Return lexical s1>s2, where trailing blanks are significant.

Defined (crosspeak cp) result logical

Defined (dimension di) result logical

Defined (nucleus nu) result logical

Defined (residue rs) result logical

Defined (sequence sq) result logical

Defined (spectrum sp) result logical

Return true if the value in the variable is defined and valid. In some circumstances, variables of these types may contain invalid values. See also the list intrinsic Defined.
