with-standard-io-syntax form* => result*

Arguments and Values:

forms---an implicit progn.

results---the values returned by the forms.


Within the dynamic extent of the body of forms, all reader/printer control variables, including any implementation-defined ones not specified by this standard, are bound to values that produce standard read/print behavior. The values for the variables specified by this standard are listed in the next figure.
