Reader Feedback and Insights: Splitting a Qshell Variable

August 30, 2002 Timothy Prickett Morgan

Hey, Ted:

The tech tip for splitting a Qshell variable is certainly one way to do it, but it seems to me a roundabout approach.

My first thought would be to use the “split” command in awk, but awk does not seem to be a supported language in Qshell.

Instead, I would use the “cut” command, which is supplied along with Qshell. Something like this example:

first=$(echo $name | cut -d " " -f 1)
last=$(echo $name | cut -d " " -f 2)

We have to pipe the variable into the “cut” command because cut normally works on

Adding Subprocedures to a Service Program

Hey, Ted:

I’m still new to ILE, procedures, and service programs. I thought you could add procedures to the end of a service program, then recreate the service program and use it without recreating any existing program that has it bound in. Is this true, or am I off track?

You need to learn and use binder language, Tim.

Here’s an example that I hope will help you get started.

Once there was an RPG programmer named Dan D. Koder. Dan decided to create a service program for frequently used math routines.

Here’s the source code:

H nomain                                     

 

A Fuzzy Search Algorithm

August 30, 2002 Timothy Prickett Morgan

Hey, Ted:

Most inquiry programs require a user to enter the exact value or exact beginning portion of a value to be located. Unfortunately such programs do not find the desired data if the user doesn’t remember the exact spelling of the search term. I have an algorithm that allows searching by any portion of a database field, even if the user misspells the search argument.

According to this algorithm, the position of each character of the input value is to be compared with the position of the same characters found in the corresponding field from the file. It calculates
