Can somebody help me I am really confused!!!!

We are currently running a vendors software which you can invoke your own programs from. When I invoke my own program I pass a field as a parameter. I then use this parameter to run another program from which I can then run various options.

In the vendors software the following runs my program:

IF STYLESUM=alltrim('Export Costing')
	exportcost(workstyle.mainkey)
ENDIF

The value of workstyle.mainkey = "T59*AU04*NEIL6803T*TECHNICAL"

My program exportcost then accepts the parameter for mainkey and then invokes a routine to run an external application

LPARAMETERS cMainkey
! /N U:\questpdm\costings.exe &cMainkey 

The value of mainkey = "T59*AU04*NEIL6803T*TECHNICAL"

In the main form of my costings.exe program at the start I then accept the parameter i.e.

parameters cMainkey

The problem I have is that the value of mainkey is "T59*AU04*NEIL6803T*TECHN"

Has anybody experienced the same kind of problem. Its chopping some characters off my mainkey when passing parameters. I am really confused!!!

Any help would be greatly appreciated!

Many Thanks
