Syntax:
with-standard-io-syntax form* => result*
Arguments and Values:
forms---an implicit progn.
results---the values returned by the forms.
Description:
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.
Variable Value *package* The CL-USER package *print-array* t *print-base* 10 *print-case* :upcase *print-circle* nil *print-escape* t *print-gensym* t *print-length* nil *print-level* nil *print-lines* nil *print-miser-width* nil *print-pprint-dispatch* The standard pprint dispatch table *print-pretty* nil *print-radix* nil *print-readably* t *print-right-margin* nil *read-base* 10 *read-default-float-format* single-float *read-eval* t *read-suppress* nil *readtable* The standard readtable
