Storing / Retrieving a letter in a variable?

[ghyman]

I am writing a series of subprograms to track tool life and wear offset adjustments over the course of several long-running jobs.
One of the subprograms will output (via DPRNT) the collected data on a regular basis; this subprogram is generic and can be called from any part programs as required.
The part program will store the part number, job number, etc as variables which the reporting subprogram can use when it generates its output.
What I would *like* to do is also be able to output the drawing revision.
Some of our customers use a numeric system for drawing revisions, which is no trouble at all to store/retrieve.
However, a large number of our customers use letters... e.g. "REV D".
I have not been able to figure out a way to handle this.


Section from part program:
#599=2137649(PART NUMBER)
#598=20(SEQ NUMBER)
#596=134558.09(JOB/LOT NUMBER)


Subprogram segment:
DPRNT[PART NUMBER #599[80] REV NO ????[20]]
DPRNT[JOB NO #596[52] SEQ NO #598[40]]
DPRNT[MACHINE NUMBER #6026[80]]

Something to mull over...

You could possibly store a number from 1 to 26, then use that value to pick one of several DPRNT statements.

IF[#20EQ1]GOTO1001(A)
IF[#20EQ2]GOTO1002(B)
...
...
...
IF[#20EQ26]GOTO1026(Z)


(START OF LETTERS)

N1000(NO REV)
DPRNT[PART NUMBER #599[80]]
GOTO1027

N1001(A)
DPRNT[PART NUMBER #599[80] REV NO A]
GOTO1027

N1002(B)
DPRNT[PART NUMBER #599[80] REV NO B]
GOTO1027
...
...
N1026(Z)
DPRNT[PART NUMBER #599[80] REV NO Z]

N1027(REMAINING DPRNTS)
DPRNT[JOB NO #596[52] SEQ NO #598[40]]
DPRNT[MACHINE NUMBER #6026[80]]

Thank you, dcoupar. That was what I figured the answer would be; just thought I'd pick the brains here.
