how to read a dataset with ampersands

Postby educ99 » Tue Sep 28, 2010 8:06 am

I have a problem. I have to read a dataset that contains many ampersands in its records.
I have to do that using a CLIST.
When CLIST finds a ampersand, occurs a error because CLIST thinks that the ampersand is a variable.

How can I read these records?
Is there a way to change the first character of a variable (the ampersand) within a CLIST?

Excuse-me by my English, my native idiom is Portuguese from Brazil.

Hello and welcome to the forum,

Please do not post the same question in multiple parts of the forum - the duplicate has been deleted.

Excuse-me by my English, my native idiom is Portuguese from Brazil.
Not to worry - many here do not have English as their first language :)

Is CLIST only to be used or might this be done with REXX?

Is this an existing CLIST or new code for this requirement.

How is the data being read?
Hope this helps,
d.sch.

Thanks.
I've posted twice because I haven't seen this more appropriate topic.
I have to use CLIST because I don't know REXX.
I'm doing a new code.
I'm reading PDS JCL members, finding some string and changing it.
The CLIST works very well, but when it find a ampersand, it fails.

What fails? The CList or the edit of the member? What is the error message?
The problem I have is that people can explain things quickly but I can only comprehend slowly.

The CLIST fails.
Ex:
LINE in the member:
//SYSUT1 DD DSN=&&TEMP

CLIST:
SET VAR1=&STR(&SUBSTR(17:21,&STR(&LINE))

The value of the SUBSTR = &&TEMP

The CLIST expect a variable named &TEMP, then it fails.

I haven't used CLIST in about 20 years so I do not know how you can check for && in var1. But if you can then just substr from position 2. Or learn Rexx :-)

Return to CLIST & REXX
