You mean the READP command?

Trevor - you wouldn't have any CL code to read a file backwards, would
you? :)

This is very rough and untested, but it looks like you need a
subprocedure like this:

p FindValue b

d pi 9 4
d InValue 10A
d InString 100A

d Posn s 5i 0
d ValueEq s 10A

/free
ValueEq = InValue + '=';

Posn = %Scan(InString: Value2);

If Posn = 0;
Return 0;
Else;
Return %Dec(InString: Posn + 1: %Check(InString:
Posn+1:'0123456789') - 1);
EndIf;

/end-free

Then you can do:

Number = FindValue(Code: String);

Subject: Extract some numeric fields from a string

Given a 60 character string that looks like this (and there will be
trailing blanks):

L=19.3000A=19.43M=21.7700LS=19.93AS=19.93CB=19.1600

How would I extract the numeric data behind one of these character
interludes into a decimal field?

For example, one time I may want to know what's behind the "M=",

another

time what's behind the "AS=", etc.

Wanting to know what's behind the "M=" means I want the value (in this
instance) of 21.7700 put into a decimal field.

Wanting to know what's behind the "AS=" means I want the value (in

this

instance) of 19.93 put into a decimal field.

At one time or another I will want to know any one of the 6 "fields"

that string. The fields are optional in the string, ie, the "CB=" may
not
be there, in which case I want that field to default to 0.

V7R1. I have the SQL Development Kit if there is some slick way with
SQL
to get one or all of these fields out of the string in one fell swoop.
