Create Tape files in Assembler

I need to create tape files in assembler code. I have a similar code to create PS DASD file using assembler code. I tried to change the code, by altering the UNIT parameter from TPUB to TAPE. But it doesnt work.

Assembler code for UNIT parameter of DASD file:
TEXT12 DS 0F
DC XL2'0015'
DC XL2'0001'
DC XL2'0008'
DC CL8'TPUB '
I tried with:
TEXT12 DS 0F
DC XL2'0015'
DC XL2'0001'
DC XL2'0008'
DC CL8'TAPE '
Please advice.

Hello,

If you want help from the forum, you cannot post "it doesn't work". . .

You have to explain the error or abend and post the appropriate diagnostic info presented by the system.

Why is a unit specified? Actually, Why is the DCB macro not used?

For many, many years device independence has been most useful. Why write new code that is now device dependent?

Did the program run to give a Dynamic Allocation error message? What was it?

There may be other text units that are incompatible with TAPE device.

Have you read the IBM MVS Authorized Assembler Services Guide? DYNALLOC error msgs and explanation is there.
