Chapter 2 Program Instructions

MAP

Field of Application

Statement for changing the ASCII value of a character when received

on the standard IN channel, or optionally on another specified

communication channel.

Syntax MAP[<nexp

>,]<nexp

>,<nexp

<nexp

> optionally speciﬁ es a communication channel:

0 = "console:"

1 = "uart1:"

2 = "uart2:"

3 = "uart3:"

4 = "centronics:"

5 = "net1:"

6 = "usb1:"

Default: Standard I/O channel.

<nexp

> is the original ASCII decimal value.

<nexp

> is the new ASCII decimal value after mapping.

Remarks

This statement is used to modify a character set (see NASC and NASCD

statements) or to ﬁ lter out undesired character. If you for example want a

“Q” (ASCII 81 dec.) to be printed as the letter “Z” (ASCII 90 dec.), the

MAP statement should be entered as:

MAP 81,90

The mapping interprets any ASCII 81 dec. value received on the standard IN

channel as ASCII 90 dec., that is when you press “Q” on the keyboard of the

host, the character “Z” will be printed (see note). However, pressing “Z” will

still produce a “Z”, because that character has not been remapped.

To reset the mapping performed above, map the character back to its

original ASCII value like this:

MAP 81,81

When a character is received by the printer, it is processed in regard

of possible MAP statements before it “enters” the Intermec Fingerprint

ﬁ rmware. That allows you to ﬁ lter out undesired control characters, which

may confuse the Intermec Fingerprint ﬁ rmware, for example by mapping

them as NUL (ASCII 0 decimal).

After processing, the selected character set (see NASC and NASCD

statements) controls how characters will be printed or displayed. If none

of the character sets meets your demands completely, use MAP statements

to modify the set that comes closest. Note that MAP statements will be

processed before any COMSET or ON KEY..GOSUB strings are checked.

NASC and NASCD statements will be processed last.

Do not map any characters to ASCII values occupied by characters used

in Intermec Fingerprint instructions, for example keywords, operators,

%, $, #, and certain punctuation marks. Mapping will be reset to normal

at power-up or reboot.
