One-Character Unsigned Binary Operators

TAL

A one-character signed binary operator can have one embedded space character

between the operator character and the closing quotation mark. For example:

a := a ‘+ ‘ 1; ! Space allowed between + and final ‘

pTAL

A one-character signed binary operator cannot have anything between the operator

character and the closing quotation mark.

For example, you must change the TAL statement:

a := a '+ ' 1;

to:

a := a '+' 1;

Bit-Extract Operators

TAL

A bit-extract operator can be immediately followed by any binary operator. For

example:

INT i;

i := i.<8>= 3; ! Space not required between <8> and =

i := i.<0:7>>> 8; ! Space not required between <0:7> and >>

pTAL

A bit-extract operator must be separated by at least one space character from these

binary operators:

For example:

INT i;

i := i.<8> = 3; ! Space required between <8> and =

i := i.<0:7> >> 8; ! Space required between <0:7> and >>
