Use in Computer Software
The dollar sign "$" has Unicode code point U+0024 (inherited from Latin-1). There are not separate characters for one and two line variants.
As the dollar sign is one of the few symbols that is, on one hand, almost universally present in computer character sets, but, on the other hand, rarely needed in their literal meaning within computer software, the $ character has been used on computers for many purposes unrelated to money. Its uses in programming languages have often influenced or provoked its uses in operating systems, and applications.

Famous quotes containing the word computer:
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
