| I ran a job with TYPRUN=SCAN and it did check only the syntax of my Jcl. My understanding is both TYPRUN=SCAN and JJSCAN do the same functionality but one is doing as Batch syntax checking & the other one is doing online. Please correct me if i am incorrect. Apart from that, is there any other functional difference between these two ? |

JJSCAN is a vendor product and such products are not a standard JCL/mainframe feature while TYPRUN=SCAN is.
About the functional difference; I can think of this one-
TYPRUN passes your JCL through converter and evaluates the JCL statements on the left side of the expressions. Which means, TYPRUN=SCAN won't be able to find errors such as file does't exist. It will however, pass the DSN name through a syntax check which evaluates if file name is less than 44 characters and each node name is less than or equal to eight characters etc.
Products such as CA JCLCheck are capable of catching such errors (file with DISP=OLD doesn't exist) beforehand. Many shops have macros with names JJSCAN, EJCK, JPREP which basically invoke JCLCheck or equivalent product in foreground mode. However, these products can also be invoked in batch mode, much like the TYPRUN. You should find out which product is installed on your site and check it out yourself. |

Because both of them have the word "SCAN" in them, that does not mean they are "same". As Abhijit has mentioned that one is a vendor product similar to JEM, JSCAN, JJ, JPREP or similar while other is not. What if your shop had JEM or JJ, had you had the same question!

| Yes you are right agkshirsagar. TYPRUN does only the syntax checking... |

| Does any one have an idea what these utilities cost (annual license)? JJ, JScan, etc? |

| The license fees are based upon a variety of factors, such as the size of the machine, the contract the site has with the vendor, and so forth. One site's charge for the same software could vary quite a bit from another site. Your best bet is to contact the vendor and request a price quote. |

Thanks, I was just looking for an off the cuff ball park figure. I understand pricing is often variable and protected information, I was just hoping someone would pop off a number  |

Why? Any number you are given is totally irrelevant and useless. You would need to get a quote from your site's vendor to have a number that makes any sense at all.
The general rule of thumb is that mainframe software packages will cost in the low tens of thousands of U.S. dollars to the seven-digit range, depending upon (as I said) a myriad factors, although there are some exceptions (some of the mainframe software is as cheap as $10,000 or so). |
