### PMAP

Maps coordinates between view and physical mapping.

**Syntax:**

**Usage:**

`
`

*result*=

**PMap**(

*coord*,

*func*)

**Parameters:**

*coord*
An expression indicating the coordinate to be mapped.

*func*
The mapping function number to be applied to given coordinate.

**Return Value:**

The mapped coordinate value.

**Description:**

This function converts a coordinate between view (as defined by the

`Window`statement) and physical (as set by the`View (Graphics)`statement) mappings. Depending on the value of`,`*func*`is used to compute a different mapping to be returned by`*expr*`:`**PMap**func value: | return value: |

0 | Treats expr as x view coordinate and returns corresponding x physical coordinate. |

1 | Treats expr as y view coordinate and returns corresponding y physical coordinate. |

2 | Treats expr as x physical coordinate and returns corresponding x view coordinate. |

3 | Treats expr as y physical coordinate and returns corresponding y view coordinate. |

**Examples:**

Screen 12

Window Screen (0, 0)-(100, 100)

Print "Logical x=50, Physical x="; PMap(50, 0) '' 320

Print "Logical y=50, Physical y="; PMap(50, 1) '' 240

Print "Physical x=160, Logical x="; PMap(160, 2) '' 25

Print "Physical y=60, Logical y="; PMap(60, 3) '' 12.5

Sleep

Window Screen (0, 0)-(100, 100)

Print "Logical x=50, Physical x="; PMap(50, 0) '' 320

Print "Logical y=50, Physical y="; PMap(50, 1) '' 240

Print "Physical x=160, Logical x="; PMap(160, 2) '' 25

Print "Physical y=60, Logical y="; PMap(60, 3) '' 12.5

Sleep
