Equal

Syntax: z = x == y == ...; z = Equal( x, y, ... )

Description: Returns 1 if each argument is equal to the next argument; returns 0 otherwise.

JMP Version Added: Before version 14

1 == 1;

Greater

Syntax: z = x > y > ... ; z = Greater( x, y, ... )

Description: Returns 1 if each argument is greater than the next argument; returns 0 otherwise.

JMP Version Added: Before version 14

3 > 2 > 1;

Greater or Equal

Syntax: z = x >= y >= ... ; z = Greater or Equal( x, y, ... )

Description: Returns 1 if each argument is greater than or equal to the next argument; returns 0 otherwise.

JMP Version Added: Before version 14

3 >= 2 >= 2;

Is Missing

Syntax: y = Is Missing( x )

Description: Returns 1 if the x argument is a missing value; returns 0 otherwise.

JMP Version Added: Before version 14

Is Missing( . );

Is Same Color

Syntax: x = Is Same Color( color1, color2, ... )

Description: Compares colors for equality.

Less

Syntax: z = x < y < ... ; z = Less( x, y, ... )

Description: Returns 1 if each argument is less than the next argument; returns 0 otherwise.

JMP Version Added: Before version 14

[1 1 1] < [0 1 2];

Less LessEqual

Syntax: z = x < y <= ... ; z = Less LessEqual( x, y, ... )

Description: Returns 1 if the first argument is less than the second argument and each argument except the first is less than or equal to the next argument; returns 0 otherwise.

JMP Version Added: Before version 14

1 < 2 <= 2;

Less or Equal

Syntax: z = x <= y <= ... ; z = Less or Equal( x, y, ... )

JMP Version Added: Before version 14

1 <= 2 <= 2;

LessEqual Less

Syntax: z = x <= y < ... ; z = LessEqual Less( x, y, ... )

Description: Returns 1 if the first argument is less than or equal to the second argument and each argument except the first is less than the next argument; returns 0 otherwise.

JMP Version Added: Before version 14

Not Equal

Syntax: z = x != y != ...; z = Not Equal( x, y, ... )
