\BQuestion:

I wrote a paragraph like

$var = 120

to assign \120 to \$var, but when I used it like in

The variable was set to $var.

\$var was not replaced by the value.

\BAnswer:

Just remove the spaces around the "=":

$var=120

\BDiscussion:

Because \PerlPoint::Parser has to recognize PerlPoint controls amidst natural language it cannot handle whitespaces as programming language parsers do - whitespaces are real tokens. Not accepting them in an assignment simplifies the parsers paragraph type detection.
