I tried to insert the YYYYMM (Current Year and Month) value in a VB record file(LERCL = 2000, RECFM=VB). A particular record size is 88. The exact value to be inserted in that record is "CP=200906'. After insertion of the above given 9 character string, what happens is the last 9 characters are truncated?

Kindly help me onto this issue.

review Your understanding of how variable length records work, please

the 2000 is the maximum logical record length, it is used/defined so that the program can properly allocate buffers for record processing

You should have defined in Your program an area 2000 bytes long

when You read/get the 88 bytes record, the length variable will contain 88

the record You try to build will be 88 + 9 ==> 97

You should change the record length var to 97 so that the write/put will write the correct record

/rant on
I wish that organization using VB record would give their employees proper training
all it takes is a handful of code snippets and samples
/rant off

thanks enrico,

if thats the case, then how to change the record length?

what happens is that there are so many records of different sizes and this happens to be of size 88 bytes.

the language of reference is PLI. they are not capturing the record length anywhere in the code.

meditate on the record definition, should be a VARYING thing

a VARYING thing is structured as a 2 bytes binary length followed by data

Your buffer should be defined accordingly
